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 is the Best Knower of you; if He willeth He will have mercy upon you, or if He willeth He will torment you. And We have not sent thee over them as a trustee. 54 And your Lord best knows those who are in the heavens and the earth; and certainly We have made some of the prophets to excel others, and to Dawood We gave a scripture. 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 they call upon are themselves seeking the means to come to their Lord, which of them shall be nearer; they hope for His mercy, and fear His chastisement. Surely thy Lord's chastisement is a thing to beware of. 57 There is not a town but We shall destroy it or upon which We shall inflict severe chastisement before the Day of Resurrection. This is written down in the Eternal Book (of Allah). 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
