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 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 And thy Lord knows very well all who are in the heavens and the earth; and We have preferred some Prophets over others; and We gave to David Psalms. 55 Say: "Call those whom you imagine to be gods besides Him; yet they have no power to relieve you of any distress or to avert it." 56 Those whom they invoke are themselves seeking a way of approach to their Lord, vying with each other to be near Him. They hope for His mercy and fear His punishment. Surely, the punishment of your Lord is to be feared: 57 The decree that all the towns were to be destroyed or afflicted with severe punishment was already written in the Book before the Day of Judgment. 58 And naught hindered Us from sending the signs except that the ancients belied them. And We vouchsafed unto Thamud a she-camel as an illumination, but they did her wrong. And We send not the signs save to frighten. 59 And recall when We said to you, (O Muhammad), that your Lord encompasses these people; and that We have made that vision that We have shown you, and the tree accursed in the Qur'an, but as a trial for people. We go about warning them, but each warning leads them to greater transgression. 60
