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 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". 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.
Migration
After Muhammad declared his Prophethood, Umm Ayman became one of his first followers. Later, she migrated to Medina.
Participation in battles
Umm Ayman was present at the Battle of Uhud. She fetched water for the soldiers and helped treat the injured. She also accompanied Muhammad in the Battle of Khaybar. 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 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, CaliphsAbu 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. A few hadith have been narrated from her. Those such as Anas ibn Malik, Abu Yazid Madani and Hanash bin Abdullah San'any have narrated from her.
Death
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.
