And say to My servants (that) they speak that which is best; surely the Shaitan sows dissensions among them; surely the Shaitan is an open enemy to man. 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 We have given preference to some Prophets over others and We gave the psalms to David. 55 Say: "Call on those - besides Him - whom ye fancy: they have neither the power to remove your troubles from you nor to change them." 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 Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn. 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
