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 best, if He will, He will have mercy on you, or if He will, He will punish you. And We have not sent you (O Muhammad SAW) as a guardian over them. 54 And it is your Lord that knoweth best all beings that are in the heavens and on earth: We did bestow on some prophets more (and other) gifts than on others: and We gave to David (the gift of) the Psalms. 55 Say (O Muhammad SAW): "Call unto those besides Him whom you pretend [to be gods like angels, Iesa (Jesus), 'Uzair (Ezra), etc.]. They have neither the power to remove the adversity from you nor even to shift it from you to another person." 56 Those unto whom they cry seek the way of approach to their Lord, which of them shall be the nearest; they hope for His mercy and they fear His doom. Lo! the doom of thy Lord is to be shunned. 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 Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn. 59 We told you that your Lord encompasses mankind. We granted the vision which We showed you, as well as the tree that is cursed in the Quran, only as a test for mankind. We warn them, but this only increases their insolence. 60
