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 It is your Lord that knoweth you best: If He please, He granteth you mercy, or if He please, punishment: We have not sent thee to be a disposer of their affairs for 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 [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 And We remained constrained from sending such signs, because the former people denied them; and We gave the Thamud the she-camel for enlightenment, so they oppressed it; and We do not send such signs except to warn. 59 And lo! We said unto thee, [O Prophet:] "Behold, thy Sustainer encompasses all mankind [within His knowledge and might]: and so We have ordained that the vision which We have shown thee - as also the tree [of hell,] cursed in this Qur'an - shall be but a trial for men. Now [by Our mentioning hell] We convey a warning to them: but [if they are bent on denying the truth,] this [warning] only increases their gross, overweening arrogance." 60
