Mother of the Prophet Muhammad ﷺ. Married Abdullāh ibn ʿAbd al-Muṭṭalib c. 569 CE. Her husband died on a trade journey to Yathrib before the Prophet ﷺ was born. She raised the Prophet ﷺ as a young child but died at al-Abwāʾ on the way back from a visit to her late husband's family in Yathrib, when the Prophet was 6 years old. He visited her grave decades later in 6 AH and wept.
