And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy. 53 Your Lord knows you very well; if He will, He will have mercy on you, or, if He will, He will chastise you. We sent thee not to be a guardian over them. 54 Your Lord knows very well all who are in the heavens and the earth. We have preferred some Prophets above others, and to David We gave the Psalms. 55 Say: Cry unto those (saints and angels) whom ye assume (to be gods) beside Him, yet they have no power to rid you of misfortune nor to change. 56 The devoted bondmen whom these disbelievers worship, themselves seek the means of proximity from their Lord, that who among them is the closest (to his Lord), and hope for His mercy and fear His punishment; indeed the punishment of your Lord is to be feared. 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 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 (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
