As soon as Hafsa had completed her waiting period, her father Umar offered her hand to Uthman Ibn 'Affan, and thereafter to Abu Bakr; but they both refused her. When Umar went to Muhammad to complain about this, Muhammad replied, "Allah will marry Uthman to better than your daughter and will marry your daughter to better than Uthman."
Muhammad married Hafsa in Shaaban AH 3 (late January or early February 625). This marriage "gave the Prophet the chance of allying himself with this faithful follower," i.e., Umar, who now became his father-in-law.
According to Islamic tradition, Hafsa had memorized the Qur'an. The copy of Zayd ibn Thabit, which was recorded on the instructions of Abu Bakr, was kept in Hafsa's house. Uthman, when he became Caliph, used Hafsa's copy when he standardized the text of the Qur'an. She is also said to have narrated sixty hadith from Muhammad.
She died in Shaban AH 45, i.e., in October or November 665. She is buried in Jannat-Ul-Baqi next to the other Mothers of the Faithful.
