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 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 Call upon those you claim to be deities besides God and you will know that they have no power to remove affliction from you or to bring about any change [that you may desire]. 56 Those whom they call upon are themselves seeking the means of access to their Lord, each trying to be nearer to Him. They crave for His Mercy and dread His chastisement. Surely your Lord's punishment 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 lo! We said unto thee, [O Prophet:] "Behold, thy Sustainer encompasses all mankind [within His knowledge and might]: and so We have ordained that the vision which We have shown thee - as also the tree [of hell,] cursed in this Qur'an - shall be but a trial for men. Now [by Our mentioning hell] We convey a warning to them: but [if they are bent on denying the truth,] this [warning] only increases their gross, overweening arrogance." 60
