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 wills and chastise you if He wills. We have not sent you, (O Muhammad), as an overseer over 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 whom you assert besides Him, so they shall not control the removal of distress from you nor (its) transference. 56 Those they call upon are themselves seeking the means to come to their Lord, which of them shall be nearer; they hope for His mercy, and fear His chastisement. Surely thy Lord's chastisement is a thing to beware of. 57 And there is no city but that We will destroy it before the Day of Resurrection or punish it with a severe punishment. That has ever been in the Register inscribed. 58 Nothing could stop Us from sending signs except that the earlier people had rejected them as lies. We sent to Thamud the she-camel as a token to make it clear to them, but they treated her cruelly; and We send signs only to deter. 59 And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra') but a trial for mankind, and likewise the accursed tree (Zaqqum, mentioned) in the Quran. We warn and make them afraid but it only increases them in naught save great disbelief, oppression and disobedience to Allah. 60
