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 very well; if He will, He will have mercy on you, or, if He will, He will chastise you. We sent thee not to be a guardian over them. 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 Proclaim, “Call upon those whom you assume besides Allah – so they do not have any power to relieve the misfortune from you nor to avert it.” 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 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 Nothing has prevented Us from sending signs, except the fact that previous peoples denied them. We gave the people of Thamud the she-camel as a clear sign, yet they mistreated her. We give signs only by way of warning. 59 And recall what time We said unto thee: verily thy Lord hath encompassed mankind. And We made the vision We shewed thee but a temptation for men, and likewise the tree accurst in the Qur'an. And We frighten them, but it only increaseth them in exorbitance great. 60
