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 It is your Lord that knoweth you best: If He please, He granteth you mercy, or if He please, punishment: We have not sent thee to be a disposer of their affairs for them. 54 Your Lord knows very well all who are in the heavens and the earth. We have preferred some Prophets above others, and to David We gave the 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 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 And [bear in mind:] there is no community which We will not destroy before the Day of Resurrection, or chastise [even earlier, if it proves sinful,] with suffering severe: all this is laid down in Our decree. 58 And nothing stops Us from sending the Ayat (proofs, evidences, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction). 59 And recall when We said to you, (O Muhammad), that your Lord encompasses these people; and that We have made that vision that We have shown you, and the tree accursed in the Qur'an, but as a trial for people. We go about warning them, but each warning leads them to greater transgression. 60
