(Muhammad), tell My servants to say what is best. Satan sows dissension among them; he is the sworn enemy of human beings. 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 thine Lord is the Best Knower of those who are in the heavens and the earth. And assuredly We have preferred some prophets over some others: and We vouchsafed unto Daud a Scripture. 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 a means to come to their Lord, competing with each other to be nearer; they hope for His Mercy and fear His punishment. Indeed, the punishment of your Lord is the subject of caution. 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 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 (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
