Hadhrat Khadijah (Radhiyallaho anha) was the first among them. At the time of her marriage, she was 40 year old and the Prophet Mohammad (Sallallaho Alaihe Wasallam) was twenty-five. She begot all his children, except a son, Ibrahim.
She was first to be married to Waraqah bin Naufal, but this marriage could not take place. Her first husband was Atiq bin Aa'iz. She had a daughter from him, whose name was Hind. Hind grew up and embraced Islam, and she was the mother of many children. On the death of Atiq, Khadijah (Radhiyallaho anha) was married to Abu Hala, and got two children from him viz. Hind and Halah. Hind lived up to the time of Ali's Caliphate. On the death of Abu Halah, the Prophet Mohammad (Sallallaho Alaihe Wasallam) married her as his first wife.
She died in Ramadan of the 10th year of the mission at the age of sixty-five. He loved her very much and did not marry any other woman during her life time. She was popularly called Tahirah (Clean and pure) even before Islam.
Her children from other husbands are therefore known as Banu Tahirah. Her virtues and privileges have been mentioned extensively (in Hadith). The Prophet Mohammad (Sallallaho Alaihe Wasallam) laid her in the grave with his own hands. The funeral service had not till then been enjoined.
