Say to My servants that they should (only) say those things that are best: for Satan doth sow dissensions among them: For Satan is to man an avowed enemy. 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 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 on those you asserted apart from Him; they have no power to remove affliction from you, or to transfer it. 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 Not a town is there but We are going to destroy it before the Day of Judgment or to torment it with a severe torment; that is in the Book inscribed. 58 Nothing hindered Us from sending Our Signs except that the people of olden times rejected them as lies. We publicly sent the she-camel to the Thamud to open their eyes but they wronged her. We never send Our Signs except to cause people to fear. 59 And when We said to you: Surely your Lord encompasses men; and We did not make the vision which We showed you but a trial for men and the cursed tree in the Quran as well; and We cause them to fear, but it only adds to their great inordinacy. 60
