Verily We have sent thee in truth, as a bearer of glad tidings, and as a warner: and there never was a people, without a warner having lived among them (in the past). And if they reject thee, so did their predecessors, to whom came their messengers with Clear Signs, Scriptures, and the Book illuminating. In the end did I punish those who rejected Faith: and how (terrible) was My punishment! *
