Obey Muhammad
We did not send any messenger except to be obeyed by Allah’s command. If they had come to you after wronging themselves, seeking Allah’s forgiveness, and if the Messenger had prayed for them, they would have found Allah Most Forgiving, Most Merciful.
4:64We sent no messenger save that he should be obeyed by Allah's leave. And if, when they had wronged themselves, they had but come unto thee and asked forgiveness of Allah, and asked forgiveness of the messenger, they would have found Allah Forgiving, Merciful.
