Tell My servants that they should always say what is best. Satan stirs up discord among them. Surely, Satan is an outright enemy to man. 53 It is your Lord that knoweth you best: If He please, He granteth you mercy, or if He please, punishment: We have not sent thee to be a disposer of their affairs for 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 Tell them: "Call upon those whom you fancy to be (your helpers) instead of Him! They have no power to remove any affliction from you, nor can they shift it (to any other)." 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 The decree that all the towns were to be destroyed or afflicted with severe punishment was already written in the Book before the Day of Judgment. 58 Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn. 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
