Umm Rumān Zaynab bint ‘Āmir' ibn Uwaymir ibn Abd Shams ibn Attab Al-Kinaniyah, (death 628) known by her kunyah "Umm Rumān" (Arabic: أمّ رومان زينب بنت عامر بن عويمر بن عبد شمس بن عتاب الكنانية) was a Ṣaḥābīyah of the Prophet Muhammad. She was a wife of Abu Bakr and the mother of ‘Ā’ishah, the favorite wife of prophet Muḥammad. Umm Ruman was from the tribe of Kinanah, and she was descended from Kinanah son of Khuzaimah who was the 13th paternal great grandfather of the prophet Mohammed.
Zaynab was raised within here clan called Banu Al-Harith ibn Ghanam which was a sub-clan of the Kinanah tribe. She married a young man from Al Azd tribe called ‘Abd Allāh ibn Ḥārith ibn Sakhbarah al-Azdī. They had three children, Ṭufayl, Asmā’, and ‘Abd Allāh.
At some point, Zaynab and her family moved to Mecca, where her husband ‘Abd Allah al-Azdi  became the partner and companion of Abu Bakr, who was already married to Qutaylah bint ‘Abd al-‘Uzzá. Shortly afterwards, Zaynab was widowed and left with no support. Abu Bakr then married her. They later had two children: a daughter, ‘Ā’ishah bint Abī Bakr, who married Muḥammad, and a son, ‘Abd al-Raḥmān ibn Abī Bakr.
Zaynab is said to have died in 628 even though more credible resources like Ibn Hajar al-Asqalani say that she died in 630. As she was being lowered into her grave, Muhammad said, "Anyone who wants to know what a houri looks like should look at Umm Ruman."
