(Muhammad), tell My servants to say what is best. Satan sows dissension among them; he is the sworn enemy of human beings. 53 Your Lord knows you very well; if He will, He will have mercy on you, or, if He will, He will chastise you. We sent thee not to be a guardian over them. 54 And your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms]. 55 Say: Call on those whom you assert besides Him, so they shall not control the removal of distress from you nor (its) transference. 56 Those whom they call upon are themselves seeking the means of access to their Lord, each trying to be nearer to Him. They crave for His Mercy and dread His chastisement. Surely your Lord's punishment is to be feared. 57 And there is not a town (population) but We shall destroy it before the Day of Resurrection, or punish it with a severe torment. That is written in the Book (of our Decrees) 58 And We remained constrained from sending such signs, because the former people denied them; and We gave the Thamud the she-camel for enlightenment, so they oppressed it; and We do not send such signs except to warn. 59 And (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety. 60
