Tell My worshipers, that they should say words that are the finest, satan would arouse discord among them; he is the clear enemy of mankind. 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 Your Lord knows whoever is in the heavens and the earth. We exalted some of the prophets over the others; and to David We gave the Book of Psalms. 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 whom they invoke are themselves seeking a way of approach to their Lord, vying with each other to be near Him. They hope for His mercy and fear His punishment. Surely, 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 And naught hindered Us from sending the signs except that the ancients belied them. And We vouchsafed unto Thamud a she-camel as an illumination, but they did her wrong. And We send not the signs save to frighten. 59 Behold! We told thee that thy Lord doth encompass mankind round about: We granted the vision which We showed thee, but as a trial for men,- as also the Cursed Tree (mentioned) in the Qur'an: We put terror (and warning) into them, but it only increases their inordinate transgression! 60
