And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain 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 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 [like 'Iesa (Jesus) - son of Maryam (Mary), 'Uzair (Ezra), angel, etc.] desire (for themselves) means of access to their Lord (Allah), as to which of them should be the nearest and they ['Iesa (Jesus), 'Uzair (Ezra), angels, etc.] hope for His Mercy and fear His Torment. Verily, the Torment of your Lord is something to be afraid of! 57 And there is not a town (population) but We shall destroy it before the Day of Resurrection, or punish it with a severe torment. That is written in the Book (of our Decrees) 58 Naught prevented Us from sending the signs but that the ancients cried lies to them; and We brought Thamood the She-camel visible, but they did her wrong. And We do not send the 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
