And say to My servants (that) they speak that which is best; surely the Shaitan sows dissensions among them; surely the Shaitan is an open enemy to man. 53 Your Lord is the Best Knower of you; if He willeth He will have mercy upon you, or if He willeth He will torment you. And We have not sent thee over them as a trustee. 54 Your Lord knows all who dwell in the heavens and the earth. We have exalted some Prophets over others, and We gave the Psalms to David. 55 Call upon those you claim to be deities besides God and you will know that they have no power to remove affliction from you or to bring about any change [that you may desire]. 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 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 prevented Us from sending the signs but that the ancients cried lies to them; and We brought Thamood the She-camel visible, but they did her wrong. And We do not send the signs, except to frighten. 59 And when We said to thee, 'Surely thy Lord encompasses men,' and We made the vision that We showed thee and the tree cursed in the Koran to be only a trial for men; and We frighten them, but it only increases them in great insolence. 60
