Tell My worshipers, that they should say words that are the finest, satan would arouse discord among them; he is the clear enemy of mankind. 53 Your Lord knows you better: He may have mercy on you if He please, or punish you if He will. Yet We have not sent you as warden 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, they call upon are themselves seeking a means to come to their Lord, competing with each other to be nearer; they hope for His Mercy and fear His punishment. Indeed, the punishment of your Lord is the subject of caution. 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 Nothing could stop Us from sending signs except that the earlier people had rejected them as lies. We sent to Thamud the she-camel as a token to make it clear to them, but they treated her cruelly; and We send signs only to deter. 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
