And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy. 53 Your Lord knows you well; if He wills He may have mercy upon you, or if He wills, He may punish you; and We have not sent you (O dear Prophet Mohammed – peace and blessings be upon him) as a guardian over them. 54 seeing that thy Sustainer is fully aware of [what is in the minds of] all beings that are in the heavens and on earth. But, indeed, We did endow some of the prophets more highly than others - just as We bestowed upon David a book of divine wisdom [in token of Our grace] 55 Call upon those you claim to be deities besides God and you will know that they have no power to remove affliction from you or to bring about any change [that you may desire]. 56 The devoted bondmen whom these disbelievers worship, themselves seek the means of proximity from their Lord, that who among them is the closest (to his Lord), and hope for His mercy and fear His punishment; indeed 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 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 (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety. 60
