Say to My servants that they should (only) say those things that are best: for Satan doth sow dissensions among them: For Satan is to man an avowed enemy. 53 Your Lord is fully aware of you. He may show you mercy if He will, or punish you if He will. We have not sent you as their guardian. 54 Your Lord knows all who dwell in the heavens and the earth. We have exalted some Prophets over others, and We gave the Psalms to David. 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, 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 Not a town is there but We are going to destroy it before the Day of Judgment or to torment it with a severe torment; that is in the Book inscribed. 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 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
