Say thou unto My bondmen that they should say that which is best, Verily the Satan would stir up strife between them; verily the Satan is unto men ever an enemy manifest. 53 Your Lord knows you better: He may have mercy on you if He please, or punish you if He will. Yet We have not sent you as warden over them. 54 And it is your Lord that knoweth best all beings that are in the heavens and on earth: We did bestow on some prophets more (and other) gifts than on others: and We gave to David (the gift of) the Psalms. 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 whom they call upon themselves seek access to their Lord, striving which of them shall be the nearest; and they hope for His mercy and fear His torment; verily the torment of thy Lord is ever to be guarded against. 57 And there is no such dwelling but which We shall destroy before the Day of Resurrection, or punish it severely; this is written in the Book. 58 Nothing could stop Us from sending signs except that the earlier people had rejected them as lies. We sent to Thamud the she-camel as a token to make it clear to them, but they treated her cruelly; and We send signs only to deter. 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
