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 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 to those whom you assert, other than Him. They have neither the power to remove your affliction nor to transfer it' 56 Those whom they call upon are themselves seeking the means of access to their Lord, each trying to be nearer to Him. They crave for His Mercy and dread His chastisement. Surely your Lord's punishment is to be feared. 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 nothing has prevented Us from sending [this message, like the earlier ones,] with miraculous signs [in its wake,] save [Our knowledge] that the people of olden times [only too often] gave the lie to them: thus, We provided for [the tribe of] Thamud the she-camel as a light-giving portent, and they sinned against it. And never did We send those signs for any other purpose than to convey a warning. 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
