Born in
Mecca, she was the daughter of
Uqba ibn Abu Mu'ayt and
Arwa bint Kurayz; Umm Kulthum's father Uqba was an outspoken opponent of Muhammad, but she became a Muslim before 622. She remained in Mecca after the
Hijra. After the
Treaty of Hudaybiyyah in 628, Umm Kulthum left Mecca for
Medina in the company of a man from the
Khuza'a tribe. Her brothers,
Walid and Ammara, pursued her, and she arrived in Medina only one day ahead of them. Her brothers asked Muhammad to return her to them, in accordance with the treaty, which stated that Muslims who escaped from Mecca to Medina should be returned to their families. Umm Kulthum pleaded that "women are weak" and that she might not have the strength to remain firm in her faith if she had to live among polytheists. Muhammad then announced the new revelation: Umm Kulthum was asked whether she had come to Medina "for love of Allah and his Apostle and Islam" or whether she was seeking or escaping a husband or hoping to make money. After she had passed the test, Muhammad told her brothers: "Allah has broken the treaty regarding women by what you know, so leave." Other women then followed Umm Kulthum's example and also left Mecca for Medina. == Marriage ==
