How shall Allah guide a people who disbelieved after their believing and (after) they had borne witness that the Messenger was true and clear arguments had come to them; and Allah does not guide the unjust people.

And certainly We did destroy generations before you when they were unjust, and their messengers had come to them with clear arguments, and they would not believe; thus do We recompense the guilty people.

Then did We raise up after him messengers to their people, so they came to them with clear arguments, but they would not believe in what they had rejected before; thus it is that We set seals upon the hearts of those who exceed the limits.

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.

And certainly We sent before you messengers to their people, so they came to them with clear arguments, then We gave the punishment to those who were guilty; and helping the believers is ever incumbent on Us.
