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 best. He will have mercy on you if He wills and chastise you if He wills. We have not sent you, (O Muhammad), as an overseer 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 SAY: "Call upon those [beings] whom you imagine [to be endowed with divine powers] beside Him and [you will find that] they have it not in their power to remove any affliction from you, or to shift it [elsewhere]." 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 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 58 Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn. 59 (Muhammad), We told you that your Lord has encompassed all mankind. We made the vision which We showed you and the condemned tree, mentioned in the Quran, as a trial for the human being. Even though We warn them, it only increases their rebellion. 60
