Battle of the Camel
Umm Kulthum married her father's cousin Talha ibn Ubayd-Allah, who was some forty years older than herself. She gave birth to Zakariyyah, Yusuf (who died in infancy) and Aisha. Talha was killed at the Battle of the Camel in 656. Umm Kulthum then accompanied Aisha on a pilgrimage to Mecca while she was still in her waiting period.
