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 knows you best; He will have mercy on you if He pleases, or He will chastise you if He pleases; and We have not sent you as being in charge of them. 54 We have given preference to some Prophets over others and We gave the psalms to David. 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 whom they call upon, themselves seek the means of access to their Lord-- whoever of them is nearest-- and they hope for His mercy and fear His chastisement; surely the chastisement of your Lord is a thing to be cautious of. 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 naught hindered Us from sending the signs except that the ancients belied them. And We vouchsafed unto Thamud a she-camel as an illumination, but they did her wrong. And We send not the signs save to frighten. 59 And when We said to you: Surely your Lord encompasses men; and We did not make the vision which We showed you but a trial for men and the cursed tree in the Quran as well; and We cause them to fear, but it only adds to their great inordinacy. 60
