Say thou unto My bondmen that they should say that which is best, Verily the Satan would stir up strife between them; verily the Satan is unto men ever an enemy manifest. 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 And thy Lord knows very well all who are in the heavens and the earth; and We have preferred some Prophets over others; and We gave to David Psalms. 55 Say: "Call those whom you imagine to be gods besides Him; yet they have no power to relieve you of any distress or 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 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 When We said to you: "Verily your Lord circumscribes mankind," and showed you the vision and the accursed tree of the Qur'an, it was as a bone of contention for men. Thus do We (instil) fear in them; but they only transgress the more. 60
