"When Muhammad saw Hamzah he said, ‘If Allah gives me victory over the Quraysh at any time, I shall mutilate thirty of their men!’ When the Muslims saw the rage of the Prophet they said, ‘By Allah, if we are victorious over them, we shall mutilate them in a way which no Arab has ever mutilated anybody."
