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 thine Lord is the Best Knower of those who are in the heavens and the earth. And assuredly We have preferred some prophets over some others: and We vouchsafed unto Daud a Scripture. 55 Say: "Call on those - besides Him - whom ye fancy: they have neither the power to remove your troubles from you nor to change them." 56 Those [saintly beings] whom they invoke are themselves striving to obtain their Sustainer's favour - [even] those among them who are closest [to Him] - hoping for His grace and dreading His chastisement: for, verily, thy Sustainer's chastisement is something to beware of! 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 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 (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
