Tell My worshipers, that they should say words that are the finest, satan would arouse discord among them; he is the clear enemy of mankind. 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 Your Lord knows whoever is in the heavens and the earth. We exalted some of the prophets over the others; and to David We gave the Book of Psalms. 55 Proclaim, “Call upon those whom you assume besides Allah – so they do not have any power to relieve the misfortune from you nor to avert it.” 56 Those they invoke themselves seek the way to their Lord, (striving) which one of them shall be nearest (to Him); and hope for His grace, and dread His punishment. Indeed, the punishment of your Lord is to be feared! 57 There is not a township but We shall destroy it ere the Day of Resurrection, or punish it with dire punishment. That is set forth in the Book (of Our decrees). 58 And nothing stops Us from sending the Ayat (proofs, evidences, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction). 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
