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. They had two children together: ʿAbd al-Raḥmān and Aisha.
Umm Ruman emigrated to Medina in 622, accompanied by her daughter Aisha and also by her stepchildren Asma and Abd Allah (children of Abu Bakr by other wives).
Ibn Sa'd states that Umm Ruman died in Medina in April/May 628.Nāsikh al-tavārīkh : zindagānī-i Payāmbar vol:2, 1162 However, Ibn Hajar al-Asqalani places her death in 630.
