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 most knowing of you. If He wills, He will have mercy upon you; or if He wills, He will punish you. And We have not sent you, [O Muhammad], over them as a manager. 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 Proclaim, “Call upon those whom you assume besides Allah – so they do not have any power to relieve the misfortune from you nor to avert it.” 56 Those whom they call upon themselves seek access to their Lord, striving which of them shall be the nearest; and they hope for His mercy and fear His torment; verily the torment of thy Lord is ever to be guarded against. 57 The decree that all the towns were to be destroyed or afflicted with severe punishment was already written in the Book before the Day of Judgment. 58 Nothing prevented Us from sending the signs but that the ancients belied them. To Thamood, We brought the shecamel as a visible (sign), yet they wronged her. We do not send 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
