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.

Say: Who has prohibited the embellishment of Allah which He has brought forth for His servants and the good provisions? Say: These are for the believers in the life of this world, purely (theirs) on the resurrection day; thus do We make the communications clear for a people who know.

And to Samood (We sent) their brother Salih. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord; this is (as) Allah's she-camel for you-- a sign, therefore leave her alone to pasture on Allah's earth, and do not touch her with any harm, otherwise painful chastisement will overtake you.

And recite to them the story of Nuh when he said to his people: O my people! if my stay and my reminding (you) by the communications of Allah is hard on you-- yet on Allah do I rely-- then resolve upon your affair and (gather) your associates, then let not your affair remain dubious to you, then have it executed against me and give me no respite:

So naught was the answer of his people except that they said: Slay him or burn him; then Allah delivered him from the fire; most surely there are signs in this for a people who believe.
