And say to My servants, that they say words that are kindlier. For surely Satan provokes strife between them, and Satan is ever a manifest foe to man. 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 well all those who are in the heavens and the earth; and indeed among the Prophets We gave excellence to some above others, and We gave the Zaboor to Dawud. 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 [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 And there is not a town (population) but We shall destroy it before the Day of Resurrection, or punish it with a severe torment. That is written in the Book (of our Decrees) 58 And nothing has prevented Us from sending signs except that the former peoples denied them. And We gave Thamud the she-camel as a visible sign, but they wronged her. And We send not the signs except as a warning. 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
