Has not the news of those before them come to them; of the people of Nuh and Ad and Samood, and the people of Ibrahim and the dwellers of Madyan and the overthrown cities; their messengers came to them with clear arguments; so it was not Allah Who should do them injustice, but they were unjust to themselves.

Say: I exhort you only to one thing, that rise up for Allah's sake in twos and singly, then ponder: there is no madness in your fellow-citizen; he is only a warner to you before a severe chastisement.
