The Prophet Muhammad

At the age of forty, Muhammad received his first revelation from God through the Angel Gabriel. The revelations continued for twenty-three years, and they are collectively known as the Quran

The Prophet Muhammad was a perfect example of an honest, just, merciful, compassionate, truthful, and brave human being. Though he was a man, he was far removed from all evil characteristics and strove solely for the sake of God and His reward in the Hereafter. Moreover, in all his actions and dealings, he was ever mindful and fearful of God
