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 best, if He will, He will have mercy on you, or if He will, He will punish you. And We have not sent you (O Muhammad SAW) as a guardian over them. 54 And your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms]. 55 SAY: "Call upon those [beings] whom you imagine [to be endowed with divine powers] beside Him and [you will find that] they have it not in their power to remove any affliction from you, or to shift it [elsewhere]." 56 Those they call upon are themselves seeking the means to come to their Lord, which of them shall be nearer; they hope for His mercy, and fear His chastisement. Surely thy Lord's chastisement is a thing to beware of. 57 The decree that all the towns were to be destroyed or afflicted with severe punishment was already written in the Book before the Day of Judgment. 58 And nothing has prevented Us from sending [this message, like the earlier ones,] with miraculous signs [in its wake,] save [Our knowledge] that the people of olden times [only too often] gave the lie to them: thus, We provided for [the tribe of] Thamud the she-camel as a light-giving portent, and they sinned against it. And never did We send those signs for any other purpose than to convey a warning. 59 And recall what time We said unto thee: verily thy Lord hath encompassed mankind. And We made the vision We shewed thee but a temptation for men, and likewise the tree accurst in the Qur'an. And We frighten them, but it only increaseth them in exorbitance great. 60
