ام ایمن (عربی:اُمِّ اَیمَن) با نام اصلی برکة بنت ثعلبه بن عمرو بن حصن بن مالک بن سلمة بن عمرو بن نعمان و با کنیه امالظباء زنی اهل حبشه بود که قبل از اسلام کنیز آمنه بنت وهب مادر پیامبر اسلام و پس از مرگ او کنیز خود پیامبر بود تا آنکه محمد او را آزاد کرد.
ارتباط وی با پیامبر اسلام[ویرایش]
ام ایمن از زنان صحابی، در دوران جاهلیت کنیز آمنه بنت وهب بود. پس از فوت آمنه، وی به پیامبر اسلام به ارث رسید. پس از مرگ آمنه در ابواء وی مسئولیت نگهداری از محمد را تا بزرگ شدنش بر عهده گرفت. عبدالمطلب به وی گفته بود از پسرم غفلت نکن، اهل کتاب گمان میکنند که او پیامبر این امت است. پیامبر اسلام بسیار او را دوست داشت و درباره او فرمود: «ام ایمن امی بعد امی.» یعنی «بعد از مادرم ام ایمن مادر من است.»
ازدواجها و فرزندان[ویرایش]
پیامبر پس از ازدواج با خدیجه او را آزاد کرد. در ابتدا او با عبید بن زید خزرجی ازدواج کرد که ایمن حاصل این ازدواج بود. پس از درگذشت عبید بن زید خزرجی، با زید بن حارثه پسرخوانده پیامبر اسلام ازدواج کرد که حاصل این ازدواج اسامه بن زید بود.
ارتباط با اسلام[ویرایش]
ام ایمن در دو جنگ احد و خیبر نیز حضور دشته است. پیامبر اسلام از وی به عنوان یکی از زنان اهل بهشت یاد کردهاست. او به همراه علی ابن ابی طالب تنها کسانی بودند که در قضیه فدک شهادت دادند که پیامبر فدک را به فاطمه زهرا بخشیده است.
She was an Abyssinian slave of Muhammad's parents, Abdullah ibn Abdul-Muttalib and Aminah bint Wahb. Following the death of Aminah, Barakah helped to raise Muhammad in the household of his grandfather, Abdul-Muttalib ibn Hashim. Muhammad later freed her from slavery, but she continued to serve Muhammad and his family. She was an early convert to Islam, and was present at the important battles of Uhud and Khaybar.
Following her freedom Muhammad also arranged her marriages, first to Ubayd ibn Zayd of the Banu Khazraj, with whom she had a son, Ayman ibn Ubayd, giving her the kunya Umm Ayman (meaning mother of Ayman). She was later married to the adopted son of Muhammad, Zayd ibn Harithah. Her son with Zayd, Usama ibn Zayd, served as a commander in the early Muslim army and led the Expedition of Usama bin Zayd into the Byzantine Empire.
Barakah was the daughter of Tha'alaba bin Amr, an Abyssinian. She served as a slave in the household of Abdullah ibn Abdul-Muttalib and Aminah bint Wahb. She became Muhammad's slave after the death of Aminah.
Following Aminah's death in Al-Abwa, Barakah looked after Muhammad, and moved with him to the household of his grandfather Abdul-Muttalib ibn Hashim in Mecca, where she served him during his childhood  and afterwards, in his adulthood. 
According to Ibn Kathir, Abdul-Muttalib ibn Hashim, Muhammad's paternal grandfather, had told Barakah not to neglect his grandson, especially as many of the Ahl al-Kiṫâb (Arabic: أَهـل الـكِـتـاب, People of the Book) predicted that he would be a prophet of the nation.
Marriages and children
When Muhammad married Khadija, he arranged for Barakah's freedom and marriage to a Khazrajite companion named Ubayd ibn Zaid. Through this marriage, Barakah bore a son named Ayman, and thus she was known as "Umm Ayman" ("Mother of Ayman"). Ubayd was killed fighting in the Battle of Khaybar. Ayman ibn Ubayd was later killed fighting in the Battle of Hunayn.
Muhammad's adopted son Zayd ibn Harithah later married Barakah. They had a son named Usama who appointed as an army leader by Muhammad and led the successful Expedition of Usama bin Zayd into the Byzantine Empire.
Participation in battles
In the battle of Uhud, many men ran away toward Medina after rumor of the death of Muhammad. Umm Ayman sprinkled dust on the face of some fugitives, gave them a spindle and told them: "give me your sword and [you] spin spindle." Then she went toward the battlefield along with several women. Subsequently, she was injured by an arrow which Hebban bin Araqa, an enemy soldier, shot at her.
Relationships with other early Muslims
Muhammad was fond of Umm Ayman, even calling her sister. Several hadiths describe Muhammad's esteem for her. He visited Umm Ayman at her house, and after him, Caliphs Abu Bakr and Umar did the same. In some hadith sources there is a heaven about the virtues of Umm Ayman. She is also praised in Shi'ite sources.
The exact date of Umm Ayman's death is not clear. Some have suggested that she died approximately five months after Muhammad's death. But according to ibn Sa'd, she was alive in the early days of the caliphate of Uthman.
