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 best, if He will, He will have mercy on you, or if He will, He will punish you. And We have not sent you (O Muhammad SAW) as a guardian over 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 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 unto whom they cry seek the way of approach to their Lord, which of them shall be the nearest; they hope for His mercy and they fear His doom. Lo! the doom of thy Lord is to be shunned. 57 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 58 Nothing prevented Us from sending the signs but that the ancients belied them. To Thamood, We brought the shecamel as a visible (sign), yet they wronged her. We do not send signs except to frighten. 59 And when We said to thee, 'Surely thy Lord encompasses men,' and We made the vision that We showed thee and the tree cursed in the Koran to be only a trial for men; and We frighten them, but it only increases them in great insolence. 60
