And those who have no knowledge say: Why does not Allah speak to us or a sign come to us? Even thus said those before them, the like of what they say; their hearts are all alike. Indeed We have made the communications clear for a people who are sure.

(Those are they) who said: Surely Allah has enjoined us that we should not believe in any messenger until he brings us an offering which the fire consumes. Say: Indeed, there came to you messengers before me with clear arguments and with that which you demand; why then did you kill them if you are truthful?

O you who believe! when you go to war in Allah's way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world's life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what you do.

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 they who give associates (to Allah) say: If Allah had pleased, we would not have served anything besides Allah, (neither) we nor our fathers, nor would we have prohibited anything without (order from) Him. Thus did those before them; is then aught incumbent upon the messengers except a plain delivery (of the message)?

And certainly Yusuf came to you before with clear arguments, but you ever remained in doubt as to what he brought; until when he died, you said: Allah will never raise a messenger after him. Thus does Allah cause him to err who is extravagant, a doubter
