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. He will have mercy on you if He will, or punish you if He will. We have not sent you to be their guardian. 54 Your Lord knows whoever is in the heavens and the earth. We exalted some of the prophets over the others; 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 worship seek to find intercessors for themselves with God. (They try to find out which of the intercessors) are closer to God. They have hope for His mercy and fear of His punishment; the punishment of your Lord is awesome. 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 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 (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety. 60
