غزوة خيبر
Barra's daughter Safiyya was initially married to Sallam ibn Mishkam, a leader of the Nadir. Later she married Kenana ibn al-Rabi ibn Abu al-Huqayq, who killed after the events of the Battle of Khaybar in 628. 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. Thus Barra binte Samaw'al became what is known today as a "mother-in-law" to Muhammad. However, it is not known what happened to her after 628.
