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 is Best Aware of you. If He will, He will have mercy on you, or if He will, He will punish you. We have not sent thee (O Muhammad) as a warden 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 Say: "Call on those - besides Him - whom ye fancy: they have neither the power to remove your troubles from you nor to change them." 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 And there is no city but that We will destroy it before the Day of Resurrection or punish it with a severe punishment. That has ever been in the Register inscribed. 58 We did not abstain from sending miracles to any of Our Messengers. These miracles were called lies by the people who lived in ancient times. To the people of Thamud, We sent the she-camel as a visible miracle and they did injustice to it. We only send miracles as warnings. 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
