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 Best Aware of you. If He will, He will have mercy on you, or if He will, He will punish you. We have not sent thee (O Muhammad) as a warden over them. 54 Your Lord knows best about everyone in the heavens and on the earth. We gave some prophets more than others: We gave David the Psalms. 55 Say: "Call on those - besides Him - whom ye fancy: they have neither the power to remove your troubles from you nor to change them." 56 Those [saintly beings] whom they invoke are themselves striving to obtain their Sustainer's favour - [even] those among them who are closest [to Him] - hoping for His grace and dreading His chastisement: for, verily, thy Sustainer's chastisement is something to beware of! 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 We remained constrained from sending such signs, because the former people denied them; and We gave the Thamud the she-camel for enlightenment, so they oppressed it; and We do not send such signs except to warn. 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
