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 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 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 whom you assert besides Him, so they shall not control the removal of distress from you nor (its) transference. 56 The devoted bondmen whom these disbelievers worship, themselves seek the means of proximity from their Lord, that who among them is the closest (to his Lord), and hope for His mercy and fear His punishment; indeed the punishment of your Lord is to be feared. 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 When We said to you: 'Indeed, your Lord encompasses all people' We did not make the vision which We showed to you, and the tree cursed in the Koran except to be a trial for people, and We frighten them, but it only increases them in great insolence. 60
