Then after sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the breasts.

And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:

And they shall say: We believe in it. And how shall the attaining (of faith) be possible to them from a distant place?

And if We had made it a Quran in a foreign tongue, they would certainly have said: Why have not its communications been made clear? What! a foreign (tongue) and an Arabian! Say: It is to those who believe a guidance and a healing; and (as for) those who do not believe, there is a heaviness in their ears and it is obscure to them; these shall be called to from a far-off place.
