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 Your Lord knows all who dwell in the heavens and the earth. We have exalted some Prophets over others, and We gave the Psalms to David. 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 they invoke themselves seek the way to their Lord, (striving) which one of them shall be nearest (to Him); and hope for His grace, and dread His punishment. Indeed, the punishment of your Lord is to be feared! 57 There is not a town but We shall destroy it or upon which We shall inflict severe chastisement before the Day of Resurrection. This is written down in the Eternal Book (of Allah). 58 And nothing has prevented Us from sending [this message, like the earlier ones,] with miraculous signs [in its wake,] save [Our knowledge] that the people of olden times [only too often] gave the lie to them: thus, We provided for [the tribe of] Thamud the she-camel as a light-giving portent, and they sinned against it. And never did We send those signs for any other purpose than to convey a warning. 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
