Say to My servants that they should (only) say those things that are best: for Satan doth sow dissensions among them: For Satan is to man an avowed enemy. 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 thy Lord is Best Aware of all who are in the heavens and the earth. And we preferred some of the prophets above others, and unto David We gave the Psalms. 55 Say thou: call upon those whom ye fancy beside Him; they are able neither to remove the distress from you nor to work a turning off. 56 Those, they call upon are themselves seeking a means to come to their Lord, competing with each other to be nearer; they hope for His Mercy and fear His punishment. Indeed, the punishment of your Lord is the subject of caution. 57 Not a town is there but We are going to destroy it before the Day of Judgment or to torment it with a severe torment; that is in the Book inscribed. 58 And nothing stops Us from sending the Ayat (proofs, evidences, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction). 59 And [remember, O Muhammad], when We told you, "Indeed, your Lord has encompassed the people." And We did not make the sight which We showed you except as a trial for the people, as was the accursed tree [mentioned] in the Qur'an. And We threaten them, but it increases them not except in great transgression. 60
