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 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 your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms]. 55 Say: 'Call on those you asserted apart from Him; they have no power to remove affliction from you, or to transfer it. 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 And there is not a town but We will destroy it before the day of resurrection or chastise it with a severe chastisement; this is written in the Divine ordinance. 58 And nothing stops Us from sending the Ayat (proofs, evidences, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction). 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
