And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy. 53 Your Lord knows you very well; if He will, He will have mercy on you, or, if He will, He will chastise you. We sent thee not to be a guardian over them. 54 seeing that thy Sustainer is fully aware of [what is in the minds of] all beings that are in the heavens and on earth. But, indeed, We did endow some of the prophets more highly than others - just as We bestowed upon David a book of divine wisdom [in token of Our grace] 55 Say: "Call those whom you imagine to be gods besides Him; yet they have no power to relieve you of any distress or to avert it." 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 Nothing prevented Us from sending the signs but that the ancients belied them. To Thamood, We brought the shecamel as a visible (sign), yet they wronged her. We do not send signs except to frighten. 59 And when We said to thee, 'Surely thy Lord encompasses men,' and We made the vision that We showed thee and the tree cursed in the Koran to be only a trial for men; and We frighten them, but it only increases them in great insolence. 60
