19. O People of the Scripture, Jews and Christians, My messenger Muhammad (peace be upon him) has come to you after a period when there were no messengers and when there was a real need for his mission, so that you do not say as an excuse, ‘No messenger came to us bringing good news of Allah’s reward nor any warning of His punishment’. Muhammad (peace be upon him) has come to you to give you good news of My reward and warn you of My punishment. I am able to do all things. Nothing is outside My ability. It is through My power that I sent the messengers and I sent Muhammad (peace be upon him) as the final messenger.
