أمّ كُلثُوم بنت محمد
Ummi Kulthum RA was the third daughter of the Prophet ﷺ and Khadija RA, whose engagement to a son of Abu Lahab was broken off when the Prophet ﷺ began preaching. When she and Fatima RA were escorted to Madinah after the Hijrah, al-Huwayrith ibn Nuqaydh threatened them and both fell from their mounts. After her sister Ruqayyah died in 2 AH, she married Uthman ibn Affan RA. She died during the Prophet ﷺ's lifetime, the third of his daughters to do so.
