She was an Abyssinian slave of Muhammad's parents, Abdullah ibn Abd al-Muttalib and Aminah bint Wahb.
Following the death of Aminah, Baraka helped to raise Muhammad in the household of his grandfather, Abd Al-Muttalib ibn Hashim.
[1] She served as a slave in the household of Abdullah ibn Abd al-Muttalib and Aminah bint Wahb.
[2] Following Aminah's death in Al-Abwa, Baraka looked after Muhammad, and moved with him to the household of his grandfather in Mecca, where she served him during his childhood [3] and afterwards,[4] in his adulthood.
[5] According to Ibn Kathir, Abd al-Muttalib, Muhammad's paternal grandfather, had told Baraka 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.
[6] When Muhammad married Khadija, he arranged for Baraka's freedom and marriage to a Khazrajite companion named Ubayd ibn Zayd.
[19] Those such as Anas ibn Malik, Abu Yazid Madani and Hanash bin Abdullah San'any have narrated from her.
