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 is Best Aware of you. If He will, He will have mercy on you, or if He will, He will punish you. We have not sent thee (O Muhammad) as a warden 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 they call upon are themselves seeking the means to come to their Lord, which of them shall be nearer; they hope for His mercy, and fear His chastisement. Surely thy Lord's chastisement is a thing 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 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 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
