Has not the account reached you of those before you, of the people of Nuh and Ad and Samood, and those after them? None knows them but Allah. Their messengers come to them with clear arguments, but they thrust their hands into their mouths and said: Surely we deny that with which you are sent, and most surely we are in serious doubt as to that to which you invite us.

Most surely He Who has made the Quran binding on you will bring you back to the destination. Say: My Lord knows best him who has brought the guidance and him who is in manifest error.
