Barra bint Samaw'al (Arabic: بَرَّة بِنْت سَمَوْأَل, Hebrew: ברה בת שמואל Barra bat Samwal) was the mother of Safiyya bint Huyayy, a wife and prominent figure in the life of Muhammad, and she was a member of an Arab Jewish tribe that interacted with Muhammad.
Barra was the daughter of the very distinguished warrior-poet from the tribe of Banu Harith, Samaw'al ibn Adiya who was known as "Samuel the Faithful," because his son was caught outside the castle and slaughtered when he refused to turn over the treasure entrusted to him.
Barra married Huyayy ibn Akhtab, who was the chief of the Banu al-Nadir — one of the largest Jewish tribes of its time.
Barra enjoyed a prominent position in Khaybar, where her husband was acknowledged as a leader and where their Abu'l-Huqayq kin owned the fortress of Qamus.
Safiyya was taken prisoner along with other women of Kenana's family, but her prisoner-of-war status ended with her marriage to the Islamic prophet Muhammad.
