Zaynab was the daughter of Amir ibn Uwaymir, a member of the Al-Harith ibn Ghanam clan of the
Kinana tribe. She married twice. First, she became the second wife of al-Ḥārith ibn Sakhbarah of the
Azd tribe. Zaynab and al-Ḥārith had a son together,
Tufayl ibn al-Harith. The family migrated to
Mecca, where al-Harith became an ally of Abu Bakr. Soon afterwards, Al-Harith died, leaving Tufayl and his widowed mother completely dependent on Abu Bakr. Abu Bakr then married Umm Ruman around 601 CE. However,
Ibn Hajar al-Asqalani places her death in 630. ==References==
