Umm Kulthum bint Muhammad
Umm Kulthūm bint Muḥammad was the third daughter of the Islamic prophet Muhammad by his first wife Khadija bint Khuwaylid.
Conversion to Islam
She was born in Mecca, the fifth of their six children. She was legally married before August 610 to Utaybah ibn Abi Lahab, but the marriage was never consummated. She was still living with her parents when Muhammad was declared a prophet by God, and Umm Kulthum became a Muslim soon after her mother did.After Muhammad warned Abu Lahab of hellfire in 613, Abu Lahab told Utaybah that he would never speak to him again unless he divorced Umm Kulthum, so he did. Her maternal brother, Hind ibn Abi Hala, asked Muhammad, "Why did you separate Umm Kulthum from Utaybah?" Muhammad replied, "Allah did not allow me to marry her to a person who is not going to Paradise."
Muhammad left Mecca in September 622. Before long Zayd ibn Haritha brought instructions to Umm Kulthum and her sister Fatima to join their father in Medina. Their uncle Al-Abbas put them on a camel; but as they were setting off, Huwayrith ibn Nuqaydh goaded the animal so that it threw them to the ground. However, Umm Kulthum and Fatima arrived safely in Medina. When Muhammad conquered Mecca in 630, he sentenced Huwayrith to death for his involvement in the conspiracy to assassinate him.
