AND TELL My servants that they should speak in the most kindly manner [unto those who do not share their beliefs]: verily, Satan is always ready to stir up discord between men - for, verily, Satan is man's open foe! 53 Your Lord is most knowing of you. If He wills, He will have mercy upon you; or if He wills, He will punish you. And We have not sent you, [O Muhammad], over them as a manager. 54 Your Lord knows all who dwell in the heavens and the earth. We have exalted 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 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 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 [remember, O Muhammad], when We told you, "Indeed, your Lord has encompassed the people." And We did not make the sight which We showed you except as a trial for the people, as was the accursed tree [mentioned] in the Qur'an. And We threaten them, but it increases them not except in great transgression. 60
