And say to My servants, that they say words that are kindlier. For surely Satan provokes strife between them, and Satan is ever a manifest foe to man. 53 Your Lord knows you very well. He will have mercy on you if He will, or punish you if He will. We have not sent you to be their guardian. 54 And thine Lord is the Best Knower of those who are in the heavens and the earth. And assuredly We have preferred some prophets over some others: and We vouchsafed unto Daud a Scripture. 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 unto whom they cry seek the way of approach to their Lord, which of them shall be the nearest; they hope for His mercy and they fear His doom. Lo! the doom of thy Lord is to be shunned. 57 And there is no city but that We will destroy it before the Day of Resurrection or punish it with a severe punishment. That has ever been in the Register 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
