Tell My servants that they should always say what is best. Satan stirs up discord among them. Surely, Satan is an outright enemy to man. 53 Your Lord knows you best; He will have mercy on you if He pleases, or He will chastise you if He pleases; and We have not sent you as being in charge of 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 you asserted apart from Him; they have no power to remove affliction from you, or to transfer it. 56 Those whom they call upon do desire (for themselves) means of access to their Lord, - even those who are nearest: they hope for His Mercy and fear His Wrath: for the Wrath of thy Lord is something to take heed of. 57 There is not a town but We shall destroy it or upon which We shall inflict severe chastisement before the Day of Resurrection. This is written down in the Eternal Book (of Allah). 58 Nothing has prevented Us from sending signs, except the fact that previous peoples denied them. We gave the people of Thamud the she-camel as a clear sign, yet they mistreated her. We give signs only by way of warning. 59 And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra') but a trial for mankind, and likewise the accursed tree (Zaqqum, mentioned) in the Quran. We warn and make them afraid but it only increases them in naught save great disbelief, oppression and disobedience to Allah. 60
