(Muhammad), tell My servants to say what is best. Satan sows dissension among them; he is the sworn enemy of human beings. 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 Your Lord knows best about everyone in the heavens and on the earth. We gave some prophets more than others: We gave David the Psalms. 55 Tell them: "Call upon those whom you fancy to be (your helpers) instead of Him! They have no power to remove any affliction from you, nor can they shift it (to any other)." 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 And [bear in mind:] there is no community which We will not destroy before the Day of Resurrection, or chastise [even earlier, if it proves sinful,] with suffering severe: all this is laid down in Our decree. 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 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
