Narrated Ibn Ishaq:
The first male to believe in the Messenger of God, to pray with him, and to accept the truth of the message he brought from God was 'Ali b. Abi Talib, who at that time was ten years old.
One of the favours which God bestowed on 'Ali b. Abi Talib was that the Messenger of God was his guardian before Islam.
