Tell My worshipers, that they should say words that are the finest, satan would arouse discord among them; he is the clear enemy of mankind. 53 Your Lord is fully aware of you. He may show you mercy if He will, or punish you if He will. We have not sent you as their guardian. 54 And your Lord knows best all who are in the heavens and the earth. And indeed, We have preferred some of the Prophets above others, and to Dawud (David) We gave the Zabur (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 whom they invoke are themselves seeking a way of approach to their Lord, vying with each other to be near Him. They hope for His mercy and fear His punishment. Surely, the punishment of your Lord is to be feared: 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 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 [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
