In Makkah — prior to Hijra — Muhammad lived with his wife Khadijah bint Khuwailid. He was twenty-five and she was forty when they got married. She was the first woman he married and his only wife until she died. None of their sons lived long. Their daughters were Zainab, Ruqaiya, Umm Kulthum and Fatimah. Khadija's own generosity and moral support for Muhammad in his early stage as Prophet of Islam were invaluable to him.
