Tell My servants, (O Muhammad), to say always that which is best. Verily it is Satan who sows discord among people. Satan indeed is an open enemy to mankind. 53 Your Lord knows you best. He will have mercy on you if He wills and chastise you if He wills. We have not sent you, (O Muhammad), as an overseer over them. 54 And your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms]. 55 SAY: "Call upon those [beings] whom you imagine [to be endowed with divine powers] beside Him and [you will find that] they have it not in their power to remove any affliction from you, or to shift it [elsewhere]." 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 Naught prevented Us from sending the signs but that the ancients cried lies to them; and We brought Thamood the She-camel visible, but they did her wrong. And We do not send the 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
