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 is the Best Knower of you; if He willeth He will have mercy upon you, or if He willeth He will torment you. And We have not sent thee over them as a trustee. 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: "Call those whom you imagine to be gods besides Him; yet they have no power to relieve you of any distress or to avert it." 56 Those whom they call upon, themselves seek the means of access to their Lord-- whoever of them is nearest-- and they hope for His mercy and fear His chastisement; surely the chastisement of your Lord is a thing to be cautious of. 57 And [bear in mind:] there is no community which We will not destroy before the Day of Resurrection, or chastise [even earlier, if it proves sinful,] with suffering severe: all this is laid down in Our decree. 58 And We remained constrained from sending such signs, because the former people denied them; and We gave the Thamud the she-camel for enlightenment, so they oppressed it; and We do not send such signs except to warn. 59 (Muhammad), We told you that your Lord has encompassed all mankind. We made the vision which We showed you and the condemned tree, mentioned in the Quran, as a trial for the human being. Even though We warn them, it only increases their rebellion. 60
