Biography
She was the servant of Abu Lahab, Muhammad's paternal half-uncle. She was freed by Abu Lahab when she informed him that his brother Abdullah [ibn Abd al-Muttalib|Abdullah]'s wife Amina bint Wahb had given birth to a son, Muḥammad.Thuwaybah became Muḥammad's first nurse, after his first three days with his mother, nursing both him and her son Masrah. Thuwaybah also nursed Abu Salama, Muhammad's first cousin, as well as Hamza ibn Abd al-Muttalib, Muḥammad's paternal uncle, two years earlier: Muḥammad had said of Ḥamzah's daughter: "She is the daughter of my nursing brother."
Eventually, Halima bint Abi Dhu'ayb took over the task after a few days and nursed Muḥammad until he reached the age of weaning.
Thuwaybah became a Muslim when Muḥammad proclaimed his prophethood. Her son Masrah died before her, and she died in 7 AH.
