ابوموسی جابر بن حیان (زادهٔ حدود سال ۱۰۰ هجری شمسی معادل با ۷۲۱ میلادی در طوس – درگذشتهٔ حدود سال ۱۹۴ هجری شمسی معادل با ۸۱۵ میلادی در کوفه) دانشمند و کیمیاگر و فیلسوفایرانی بود. او را پدر یا بنیانگذار علم شیمی اولیه نامیدهاند و بسیاری از روشها (مانند تقطیر) و انواع ابزارهای اساسی شیمی مانند قرع و انبیق را به او نسبت میدهند.
ابوموسی جابر بن حیان، کیمیاگر برجستهٔ ایران، در سال صد هجری شمسی در شهر توس از توابع خراسان متولد شد. مدت کوتاهی پس از تولدش، پدر او که یک داروساز شناخته شده و پیرو مذهب شیعه بود، به دلیل نقشی که در براندازی حکومت اموی داشت، دستگیر شد و به قتل رسید.
جابر به نوشتههای باقیمانده از پدرش علاقهمند شد و به ادامهٔ حرفهٔ او پرداخت. او با شوق و علاقه به یادگیری علوم دیگر نیز میپرداخت. همین، سبب هجرت او از توس به کوفه که در آن زمان مرکز علمی جهان بود شد.
کتابها و رسالات متعدد جابر، سالها بعد از او، توجه کیمیاگران اروپایی را به خود جلب کرد و سالها از آن به عنوان منبع معتبری استفاده میکردند. به گفتهٔ آنها، این کتابها تأثیر عمیقی بر تغییر و تصحیح دیدگاه کیمیاگران غربی گذاشتهاست.
عاقبت، جابر بن حیان، در سال صد و نود و چهار ه.ش (معادل با ۸۱۵ میلادی) در شهر کوفهٔ درگذشت.
شاگردی جعفر صادق
در اعتقادات مرتبط با شیعه همواره جابر یکی از شاگردان بزرگ امام ششم شیعیانجعفر صادق معرفی میشود و آنچه مسلم است این است که جابر خود را شاگرد جعفر صادق میدانسته از سویی دیگر برخی مستشرقین غربی مانند هانری کوربن در زمینه شاگردی جابر برای جعفر صادق با احتیاط تشکیک کرده یا مانند الیزر پاول کراوس، مستشرق یهودی، آن را از اساس رد کردهاند؛ اگر چه پاسخهایی نیز در رد ادعای کراوس از جمله رساله «مسئله جابری» منتشر شدهاست.
اختلاف نظر در مورد تاریخ تولد وی
در مورد تاریخ دقیق تولد و مرگ و محل تولد وی اختلاف نظر وجود دارد.
به گفته برخی وی متولد سال ۱۰۰ هجری شمسی و وفات وی در سال ۱۹۴ هجری شمسی بودهاست.
برخی نیز او را متولد سال ۱۰۳ هجری شمسی دانسته و وفات وی را در سال ۲۰۰ هجری شمسی ذکر کردهاند.
با این حال دانشنامهٔ بریتانیکا وی را متولد سال ۷۲۱ میلادی و وفات وی را در سال ۸۱۵ میلادی (نزدیک به هزار و دویست سال پیش) ثبت کردهاست.
منزلت جابر در علم شیمی
جابربن حیان نخستین شیمیدان ایرانی است. وی اولین کسی است که به علم شیمی شهرت و آوازه بخشید و احتمالا نخستین مسلمانی است که شایستگی کسب عنوان شیمیدان را دارد.
اکسیر و عقیده جابر دربارهٔ آن
عقیده جابر این بود همچنان که طبیعت میتواند اشیاء را به یکدیگر تبدیل کند، مانند تبدیل خاک و آب به گیاه و تبدیل گیاه به موم و عسل بهوسیله زنبور عسل و تبدیل قلع به نقره در زیر زمین و … کیمیاگر نیز میتواند با تقلید از طبیعت و استفاده از تجربهها و آزمایشها همان کار طبیعت را در مدت زمانی کوتاهتر انجام دهد. اما کیمیاگر برای اینکه بتواند یک شیء را به شیء دیگر تبدیل کند، بهوسیلهای نیازمند است که اصطلاحاً آن را اکسیر مینامند.
اکسیر در علم کیمیا، به منزله دارو در علم پزشکی است. جابر اکسیر را که از آن در کارهای کیمیایی خود استفاده میکرد، از انواع موجودات سهگانه (فلزات، حیوانات و گیاهان) به دست میآورد. او خود، در این زمینه میگوید: هفت نوع اکسیر وجود دارد:
اکسیر فلزی: اکسیر بدست آمده از فلزات
اکسیر حیوانی: اکسیر بدست آمده از حیوانات
اکسیر گیاهی: اکسیر بدست آمده از گیاهان
اکسیر حیوانی - گیاهی: اکسیر بدست آمده از امتزاج مواد حیوانی و گیاهی
اکسیر فلزی - گیاهی: اکسیر بدست آمده از امتزاج مواد فلزی و گیاهی
اکسیر فلزی - حیوانی: اکسیر بدست آمده از امتزاج مواد فلزی و حیوانی
اکسیر فلزی - حیوانی - گیاهی: اکسیر بدست آمده از امتزاج مواد فلزی و گیاهی و حیوانی

عقیده جابر بن حیان دربارهٔ فلزات
جابر هفت فلز: طلا، نقره، مس، آهن، سرب، جیوه و قلع را «فلزات اصلی» میدانست. این فلزات به تعبیر جابر اساس صنعت کیمیا را تشکیل میدهند. به عبارت دیگر قوانین علم کیمیا بر این هفت فلز استوار است. با این حال، خود این کانیها از ترکیب دو کانی اساسی، یعنی گوگرد و جیوه بوجود میآیند که به نسبتهای مختلف، در دل زمین، باهم ترکیب میشوند؛ بنابراین، تفاوت میان فلزات هفتگانه تنها یک تفاوت عرضی وجود دارد نه جوهری که محصول تفاوت نسبت ترکیب گوگرد و جیوه در آن است. اما طبیعت هر یک از گوگرد و جیوه تابع دو عامل زمینی و زمانی است. به عبارت دیگر، تفاوت خاک زمینی که این دو کانی در آن بوجود میآیند و همچنین تفاوت وضعیت کواکب به هنگام پیدایش آنها موجب میشود که طبیعت گوگرد یا جیوه تفاوت پیدا کند.
تعریف جابر از بعضی فلزات و تبدیل آنها
دارای چهار طبع است. ظاهر آن، سرد و تر و نرم و باطنش گرم و خشک و سخت … پس هرگاه صفات ظاهر قلع به درون آن برده شود و صفات باطنی آن به بیرون آورده شود، ظاهرش خشک و در نتیجه قلع به آهن تبدیل میشود.
از چهار طبع پدید آمدهاست که از میان آنها، دو طبع، یعنی حرارت و خشکی شدید به ظاهر آن اختصاص دارد و دو طبع دیگر یعنی برودت و رطوبت به باطن آن. ظاهر آن، سخت و باطن آن نرم است. ظاهر هیچ جسمی به سختی ظاهر آن نیست. همچنین نرمی باطن آن به اندازه سختی ظاهرش است. از میان فلزات جیوه مانند آهن است. زیرا ظاهر آن آهن و باطن آن جیوهاست.
ظاهر آن گرم و تر و باطنش سرد و خشک است. پس جمیع اجسام (فلزات) را به این طبع برگردان. چون طبعی معتدل است.
گرم و خشک است ولی خشکی آن از خشکی آهن کمتر است زیرا طبع اصلی مس، همچون طلا، گرم و تر بودهاست اما درآمدن خشکی بر آن، آن را فاسد کردهاست؛ لذا با از میان بردن خشکی، مس به طبع اولیه خود برمیگردد.
طبع ظاهری آن سرد و تر و نرم و طبع باطنیاش گرم و خشک و سخت است؛ بنابراین ظاهر آن، همان جیوه و باطنش آهن است. برای آن که جیوه را به اصل آن یعنی طلا برگردانی، ابتدا باید آن را به نقره تبدیل کنی.
اصل نخست آن، طلا است ولی با غلبه طبایع برودت و یبوست، طلا به درون منتقل شدهاست و در نتیجه ظاهر فلز، نقره و باطن آن طلا گردیدهاست؛ بنابراین اگر بخواهی آن را به اصلش یعنی طلا برگردانی، برودت آن را به درون انتقال ده، حرارت آن آشکار میشود. سپس خشکی آن را به درون منتقل کن، در نتیجه، رطوبت آشکار و نقره تبدیل به طلا میشود.
نوآوری انواع گوناگونی از وسایل آزمایشگاهی، از جمله انبیق به اسم او ثبت شدهاست. کشف مواد شیمیایی متعددی همچون هیدرو کلریک اسید، نیتریک اسید، تیزاب (مخلوطی از دو اسید یاد شده که از جمله اندک موادی است که طلا را در خود حل میکند)، سیتریک اسید (جوهر لیمو) و استیک اسید (جوهر سرکه)، همچنین معرفی فرایندهای تبلور و تقطیر که هر دو سنگ بنای شیمی امروزی بهشمار میآیند، از جمله یافتههای اوست. او همچنین یافتههای دیگری دربارهٔ روشهای استخراج و خالص سازی طلا، جلوگیری از زنگ زدن آهن، حکاکی روی طلا، رنگرزی و نم ناپذیر کردن پارچهها و تجزیهٔ مواد شیمیایی ارائه داد. از جمله اختراعهای دیگر او، قلم نوری است. قلمی که جوهر آن در تاریکی نیز نور میدهد. (احتمالاً با استفاده از خاصیت فسفرسانس این اختراع را انجام دادهاست) در آخر، بذر دستهبندی امروزی عنصرها به فلز و نافلز را میتوان در دست نوشتههای وی یافت.

Popularly known as the father of chemistry, Jabir’s works contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound (Sal ammoniac or Ammonium chloride) from organic substances (such as plants, blood, and hair) by chemical means.
As early as the 10th century, the identity and exact corpus of works of Jabir was in dispute in Islamic circles. The authorship of all these works by a single figure, and even the existence of a historical Jabir, are also doubted by modern scholars. Instead, Jabir ibn Hayyan is seen more like a pseudonym to whom "underground writings" by various authors became ascribed.
Some Arabic Jabirian works (e.g., the “Book of Mercy”, and the “Book of Seventy”) were translated into Latin under the Latinized name "Geber", and in 13th-century Europe an anonymous writer, usually referred to as pseudo-Geber, started to produce alchemical and metallurgical writings under this name.
In 988 Ibn al-Nadim compiled the Kitab al-Fihrist which mentions Jabir as a spiritual follower, companion and as a student to Jafar as-Sadiq, the sixth Shia Imam. In another reference al-Nadim reports that a group of philosophers claimed Jabir was one of their own members. Another group, reported by al-Nadim, says only The Large Book of Mercy is genuine and that the rest are pseudographical. Their assertions are rejected by al-Nadim. Joining al-Nadim in asserting a real Jabir; Ibn-Wahshiyya ("Jaber ibn Hayyn al-Sufi ...book on poison is a great work...")
Rejecting a real Jabir; (the philosopher c. 970) Abu Sulayman al-Sijistani claims the real author is one al-Hasan ibn al-Nakad al-Mawili. The 14th century critic of Arabic literature, Jamal al-Din ibn Nubata al-Misri declares all the writings attributed to Jabir doubtful.
According to the philologist-historian Paul Kraus (1904–1944), Jabir cleverly mixed in his alchemical writings unambiguous references to the Ismaili or Qarmati movement. Kraus wrote: "Let us first notice that most of the names we find in this list have undeniable affinities with the doctrine of Shi'i Gnosis, especially with the Ismaili system." Henry Corbin believes that Jabir ibn Hayyan was an Ismaili. Jabir was a natural philosopher who lived mostly in the 8th century; he was born in Tus, Khorasan, in Persia, well known as Iran then ruled by the Umayyad Caliphate. Jabir in the classical sources has been variously attributed as al-Azdi, al-Kufi, al-Tusi, al-Sufi, al-Tartusi or al-Tarsusi, and al-Harrani. There is a difference of opinion as to whether he was an Arab from Kufa who lived in Khurasan, or a Persian from Khorasan who later went to Kufa or whether he was, as some have suggested, of Syrian Sabian origin and later lived in Persia and Iraq. In some sources, he is reported to have been the son of Hayyan al-Azdi, a pharmacist of the ArabianAzd tribe who emigrated from Yemen to Kufa (in present-day Iraq). while Henry Corbin believes Geber seems to have been a non-Arab client of the 'Azd tribe. Hayyan had supported the Abbasid revolt against the Umayyads, and was sent by them to the province of Khorasan to gather support for their cause. He was eventually caught by the Umayyads and executed. His family fled to Yemen, perhaps to some of their relatives in the Azd tribe, where Jabir grew up and studied the Quran, mathematics and other subjects. Jabir's father's profession may have contributed greatly to his interest in alchemy.
After the Abbasids took power, Jabir went back to Kufa. He began his career practicing medicine, under the patronage of a Vizir (from the noble Persian family Barmakids) of Caliph Harun al-Rashid. His connections to the Barmakid cost him dearly in the end. When that family fell from grace in 803, Jabir was placed under house arrest in Kufa, where he remained until his death.
An illustration of the various experiments and instruments used by Jabir Ibn Hayyan.
In total, nearly 3,000 treatises and articles are credited to Jabir ibn Hayyan. Following the pioneering work of Paul Kraus, who demonstrated that a corpus of some several hundred works ascribed to Jābir were probably a medley from different hands,:3 mostly dating to the late 9th and early 10th centuries, many scholars believe that many of these works consist of commentaries and additions by his followers, particularly of an Ismaili persuasion. On the other hand, contemporary scholar Syed Nomanul Haq refuses the multiplicity of authors hypothesis, and says that Kraus has misrepresented the Jabirian corpus for three main reasons : a) he hasn't inspected the bibliographies correctly, considering that there have been many leaps (in one instance, we have no titles between 500 and 530), so, all in all, the numbers are more over 500 than close to 3000 ; b) in many cases, a part or chapter of a book has been counted as a book itself, like with the Kitab al-Jumal al-'Ishrin (book of twenty maxims), which has been counted for 20 books and c) finally, many of the supposed "books" are not so in the formal sense, the Kitab al-Sahl occupying a single paragraph and many others few folios. Syed Nomanul Haq concludes that "this rough investigation makes it abundantly clear that we should view with a great deal of suspicion any arguments for a plurality of authors which is based on Kraus’ inflated estimate of the volume of the Jabirian corpus."
The 112 Books dedicated to the Barmakids, viziers of Caliph Harun al-Rashid. This group includes the Arabic version of the Emerald Tablet, an ancient work that proved a recurring foundation of and source for alchemical operations. In the Middle Ages it was translated into Latin (Tabula Smaragdina) and widely diffused among European alchemists.
The Seventy Books, most of which were translated into Latin during the Middle Ages. This group includes the Kitab al-Zuhra ("Book of Venus") and the Kitab Al-Ahjar ("Book of Stones").
The Books on Balance; this group includes his most famous 'Theory of the balance in Nature'.
Jabir states in his Book of Stones (4:12) that "The purpose is to baffle and lead into error everyone except those whom God loves and provides for". His works seem to have been deliberately written in highly esoteric code (see steganography), so that only those who had been initiated into his alchemical school could understand them. It is therefore difficult at best for the modern reader to discern which aspects of Jabir's work are to be read as ambiguous symbols, and what is to be taken literally.
A huge pseudo-epigraphic literature of alchemical books was composed in Arabic, among which the names of Persian authors also appear like Jāmāsb, Ostanes, Mani, testifying that alchemy-like operations on metals and other substances were also practiced in Persia. The great number of Persian technical names (zaybaq = mercury, nošāder = sal-ammoniac) also corroborates the idea of an important Iranian root of medieval alchemy. Ibn al-Nadim reports a dialogue between Aristotle and Ostanes, the Persian alchemist of Achaemenid era, which is in Jabirian corpus under the title of Kitab Musahhaha Aristutalis.Ruska had suggested that the Sasanian medical schools played an important role in the spread of interest in alchemy.
He emphasizes the long history of alchemy, "whose origin is Arius ... the first man who applied the first experiment on the [philosopher's] stone... and he declares that man possesses the ability to imitate the workings of Nature" (Nasr, Seyyed Hussein, Science and Civilization of Islam).
Jabir's alchemical investigations ostensibly revolved around the ultimate goal of takwin, the artificial creation of life. The Book of Assemblage "Kitāb Al-Tajmi' " includes several recipes for creating creatures such as scorpions, snakes, and even humans in a laboratory environment, which are subject to the control of their creator. What Jabir meant by these recipes is unknown.
Jabir's alchemical investigations were theoretically grounded in an elaborate numerology related to Pythagorean and Neoplatonic systems. The nature and properties of elements were defined through numeric values assigned to the Arabic consonants present in their name.
By Jabir's time Aristotelian physics had become Neoplatonic. Each Aristotelian element was composed of these qualities: fire was both hot and dry, earth, cold and dry, water cold and moist, and air, hot and moist. This came from the elementary qualities which are theoretical in nature plus substance. In metals two of these qualities were interior and two were exterior. For example, lead was cold and dry and gold was hot and moist. Thus, Jabir theorized, by rearranging the qualities of one metal, a different metal would result. Like Zosimos, Jabir believed this would require a catalyst, an al-iksir, the elusive elixir that would make this transformation possible – which in European alchemy became known as the philosopher's stone.
According to Jabir's mercury-sulfur theory, metals differ from each in so far as they contain different proportions of the sulfur and mercury. These are not the elements that we know by those names, but certain principles to which those elements are the closest approximation in nature. Based on Aristotle's "exhalation" theory the dry and moist exhalations become sulfur and mercury (sometimes called "sophic" or "philosophic" mercury and sulfur). The sulfur-mercury theory is first recorded in a 7th-century work Secret of Creation credited (falsely) to Balinus (Apollonius of Tyana). This view becomes widespread. In the Book of Explanation Jabir says
the metals are all, in essence, composed of mercury combined and coagulated with sulphur [that has risen to it in earthy, smoke-like vapors]. They differ from one another only because of the difference of their accidental qualities, and this difference is due to the difference of their sulphur, which again is caused by a variation in the soils and in their positions with respect to the heat of the sun
Holmyard says that Jabir proves by experiment that these are not ordinary sulfur and mercury.
The seeds of the modern classification of elements into metals and non-metals could be seen in his chemical nomenclature. He proposed three categories:
The origins of the idea of chemical equivalents might be traced back to Jabir, in whose time it was recognized that "a certain quantity of acid is necessary in order to neutralize a given amount of base."[verification needed]
The Jabirian corpus is renowned for its contributions to alchemy. It shows a clear recognition of the importance of experimentation, "The first essential in chemistry is that thou shouldest perform practical work and conduct experiments, for he who performs not practical work nor makes experiments will never attain to the least degree of mastery." He is credited with the use of over twenty types of now-basic chemical laboratory equipment, such as the alembic and retort, and with the description of many now-commonplace chemical processes – such as crystallisation, various forms of alchemical "distillation", and substances citric acid (the sour component of lemons and other unripe fruits), acetic acid (from vinegar) and tartaric acid (from wine-making residues), arsenic, antimony and bismuth, sulfur, and mercury that have become the foundation of today's chemistry.
"His influence may be traced throughout the whole historic course of European alchemy and chemistry."
The historian of chemistry Erick John Holmyard gives credit to Jabir for developing alchemy into an experimental science and he writes that Jabir's importance to the history of chemistry is equal to that of Robert Boyle and Antoine Lavoisier.
The historian Paul Kraus, who had studied most of Jabir's extant works in Arabic and Latin, summarized the importance of Jabir to the history of chemistry by comparing his experimental and systematic works in chemistry with that of the allegorical and unintelligible works of the ancient Greek alchemists.
The word gibberish is theorized to be derived from the Latinised version of Jabir's name, in reference to the incomprehensible technical jargon often used by alchemists, the most famous of whom was Jabir. The Oxford English Dictionary suggests the term stems from gibber; however, the first known use of the term "gibberish" dates prior to the first known use of the word "gibber".
The identity of the author of works attributed to Jabir has long been discussed. According to a famous controversy,pseudo-Geber has been considered as the unknown author of several books in Alchemy. This was first independently suggested, on textual and other grounds, by the 19th-century historians Hermann Kopp and Marcellin Berthelot. Jabir, by reputation the greatest chemist of Islam, has long been familiar to western readers under the name of Geber, which is the medieval rendering of the Arabic Jabir, the Geber of the Middle Ages.
The works in Latin corpus were considered to be translations until the studies of Kopp, Hoefer, Berthelot, and Lippman. Although they reflect earlier Arabic alchemy they are not direct translations of "Jabir" but are the work of a 13th-century Latin alchemist.
Eric Holmyard says in his book Makers of Chemistry Clarendon press.(1931).
There are, however, certain other Latin
works, entitled The Sum of Perfection, The Investigation of
Perfection, The Invention of Verity, The Book of Furnaces, and
The Testament, which pass under his name but of which no
Arabic original is known. A problem which historians of
chemistry have not yet succeeded in solving is whether these
works are genuine or not.
However, by 1957 when he (Holmyard) wrote Alchemy Holmyard had abandoned the idea of an Arabic original (although they are based on "Islamic" alchemical theories).
The question at once arises whether the Latin works are genuine translations from the Arabic, or written by a Latin author and, according to common practice, ascribed to Jabir in order to heighten their authority. That they are based on Muslim alchemical theory and practice is not questioned, but the same may be said of most Latin treatises on alchemy of that period; and from various turns of phrase it seems likely that their author could read Arabic. But the general style of the works is too clear and systematic to find a close parallel in any of the known writings of the Jabirian corpus, and we look in vain in them for any references to the characteristically Jabirian ideas of "balance" and the alphabetic numerology. Indeed for their age they have a remarkably matter of fact air about them, theory being stated with a minimum of prolixity and much precise practical detail being given. The general impression they convey is that they are the product of an occidental rather than an oriental mind, and a likely guess would be that they were written by a European scholar, possibly in Moorish Spain. Whatever their origin, they became the principal authorities in early Western alchemy and held that position for two or three centuries.
The question of Pseudo-Gebers identity was still in dispute in 1962. It is said that Geber, the Latinized form of "Jabir," was adopted presumably because of the great reputation of a supposed 8th-century alchemist by the name of Jabir ibn Hayyan. About this historical figure, however, there was considerable uncertainty a century ago, and the uncertainty continues today. This is sometimes called the "Geber-Jābir problem". It is possible that facts mentioned in the Latin works, ascribed to Geber and dating from the twelfth century and later, may be placed to Jabir's credit.
In 2005, the historian Ahmad Y. Al-Hassan pointed out that earlier Arabic texts prior to the 13th century, including the works of Jabir and Al-Razi, already contained detailed descriptions of substances such as nitric acid, aqua regia, vitriol, and various nitrates. In 2009, Al-Hassan criticized Berthelot's original hypothesis and, on textual grounds, argued that the Pseudo-Geber Corpus was originally written in Arabic. Al-Hassan criticized Berthelot's lack of familiarity with the complete Arabic corpus and pointed to various Arabic Jabirian manuscripts which already contain much of the theories and practices that Berthelot previously attributed to the Latin corpus. Regardless of the identity of pseudo-Geber, the contents of the Pseudo-Geber Corpus are mostly derived from earlier Arabic alchemy, including the work of Jabir as well as other Arabic authors such as Al-Razi.
The Latin corpus consists of books with an author named "Geber" for which researchers have failed to find a text in Arabic. These books were heavily influenced by Arabic books written by Jabir, the "real" Geber, and by Al Razi and others. They are available in Latin only, date from about the year 1310, and their author is identified as "Geber" or pseudo-Geber:
Summa perfectionis magisterii ("The Height of the Perfection of Mastery").
Liber fornacum ("Book of Furnaces"),
De investigatione perfectionis ("On the Investigation of Perfection"), and
De inventione veritatis ("On the Discovery of Truth").
The Liber fornacum, De investigatione perfectionis and De inventione veritatis "are merely extracts from or summaries of the Summa Perfectionis Magisterii with later additions." which may have been compiled by later writers.

There is a debate as to whether he was an Arab from Kufa who lived in Khurasan, or a Persian from Khorasan who later went to Kufa or whether he was, as some have suggested, of Syrian origin and later lived in Persia and Iraq".

^ ab"Iranica JAʿFAR AL-ṢĀDEQ iv. And Esoteric sciences". Retrieved 11 June 2011. The historical relations between Jaʿfar al-Ṣādeq and Jāber b. Ḥayyān remain very controversial, as they are linked to still unresolved questions about dating, composition, and authorship of the texts attributed to Jāber. Scholars such as Julius Ruska, Paul Kraus, and Pierre Lory consider Jaʿfar al-Ṣādeq’s involvement in the transmission of alchemical knowledge as a literary fiction, whereas Fuat Sezgin, Toufic Fahd, and Nomanul Haq are rather inclined to accept the existence of alchemical activity in Medina in Jaʿfar al-Ṣādeq’s time, although they remain cautious regarding the authenticity of the attribution of the Jaberian corpus to Jāber b. Ḥayyān and of the alchemical works to Jaʿfar al-Ṣādeq (Ruska, 1924, pp. 40–52; idem, 1927, pp. 264–266; Kraus, I, pp. lv-lvii; Lory, pp. 14–21, 57–59, 101–107; Sezgin, I, p. 529, IV, pp. 128–311; Fahd, 1970, pp. 139–141; Nomanul Haq, pp. 3–47).
