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 Sustainer is fully aware of what you are [and what you deserve]: if He so wills, he will bestow [His] grace upon you; and if He so wills, He will chastise you. Hence, We have not sent thee [unto men, O Prophet,] with the power to determine their fate, 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 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 [saintly beings] whom they invoke are themselves striving to obtain their Sustainer's favour - [even] those among them who are closest [to Him] - hoping for His grace and dreading His chastisement: for, verily, thy Sustainer's chastisement is something to beware of! 57 There is not a habitation We shall not destroy before the Day of Resurrection, or not inflict severe punishment upon it. This is in accordance with the law (of God). 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 (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
