Zaynab bint Khuzaymah

Zaynab bint Khuzaymah al-Hilāliyyah, of the Banū Hilāl of Najd rather than Quraysh, was known even before Islam as Umm al-Masākīn ("mother of the poor") for her generosity toward orphans and the needy, a title she carried into her life as a Muslim. She had first been married, in the days of Jāhiliyyah, to Ṭufayl ibn al-Ḥārith, the Prophet's (ﷺ) cousin, who later divorced her; she then married his brother ʿUbaydah ibn al-Ḥārith, one of the three Muslim champions (with Ḥamzah and ʿAlī) in the opening mubārazah at Badr, where he was mortally wounded and died shortly after.

Left with no family in either Makkah or Madinah, the Prophet (ﷺ) married her, probably around the third year of the Hijrah, likely for the same reason he had married Sawdah: she had no one else to provide for her. The marriage lasted only a few months, reports range from three to eight, before she died in Rabīʿ al-Awwal of the fourth year of the Hijrah. She was the only wife of the Prophet (ﷺ) to die in Madinah besides Khadījah (who died in Makkah), and the first of the Prophet's (ﷺ) wives to be buried in Baqīʿ al-Gharqad.
