(Muhammad), tell My servants to say what is best. Satan sows dissension among them; he is the sworn enemy of human beings. 53 Your Lord knows you very well. He will have mercy on you if He will, or punish you if He will. We have not sent you to be their guardian. 54 Your Lord knows all who dwell in the heavens and the earth. We have exalted some Prophets over others, and We gave the Psalms to David. 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 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 58 And nothing could have hindered Us that We should send signs except that the ancients rejected them; and We gave to Samood the she-camel-- a manifest sign-- but on her account they did injustice, and We do not send signs but to make (men) fear. 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
