Khadija -the wife of the Prophet Muhammad- was the first woman to accept his prophecy and to believe in Allah
Khadija -the wife of the Prophet Muhammad- was the first woman to accept his prophecy and to believe in Allah. She was always at her husband's side helping him through difficult times. She used to lighten his burden and offer him comfort while assuring him of her confidence in his Message.
On men`s side, Ali ibn Abi Talib -Prophet Muhammad`s cousin- was the first to accept Islam. He was ten years old at the time and living in the house of the Messenger of Allah. When Abu Talib -Prophet Muhammad`s uncle- went through a period of hardship during a famine, the Messenger of Allah had taken his son 'Ali' into his own house and brought him up. Zayd ibn Harithah, the freed slave of the Messenger of Allah -whom he had adopted- also is amongst the first Muslims.
The Islam of these people reflected the beliefs of those who knew the Messenger of Allah best. They had witnessed his truthfulness, sincerity and good behavior. The people who live in a house always know best what is in it.
