Tell My servants that they should always say what is best. Satan stirs up discord among them. Surely, Satan is an outright enemy to man. 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 whoever is in the heavens and the earth. We exalted some of the prophets over the others; 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 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 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
