And say to My servants, that they say words that are kindlier. For surely Satan provokes strife between them, and Satan is ever a manifest foe to man. 53 Your Lord knows you best; He will have mercy on you if He pleases, or He will chastise you if He pleases; and We have not sent you as being in charge of 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: Cry unto those (saints and angels) whom ye assume (to be gods) beside Him, yet they have no power to rid you of misfortune nor to change. 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 town but We shall destroy it or upon which We shall inflict severe chastisement before the Day of Resurrection. This is written down in the Eternal Book (of Allah). 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 We told you that your Lord encompasses mankind. We granted the vision which We showed you, as well as the tree that is cursed in the Quran, only as a test for mankind. We warn them, but this only increases their insolence. 60
