It is narrated from Mus'ab bin Abdullah al-Zubayri that Sayyidah Arwa bint Kurayz (may Allah be pleased with her) (who was the mother of Sayyiduna Uthman, may Allah be pleased with him) accepted Islam, emigrated to Madinah, and passed away during the caliphate of Sayyiduna Uthman (may Allah be pleased with him).
