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 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 We have given preference to some Prophets over others and We gave the psalms to David. 55 SAY: "Call upon those [beings] whom you imagine [to be endowed with divine powers] beside Him and [you will find that] they have it not in their power to remove any affliction from you, or to shift it [elsewhere]." 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 township but We shall destroy it ere the Day of Resurrection, or punish it with dire punishment. That is set forth in the Book (of Our decrees). 58 We did not abstain from sending miracles to any of Our Messengers. These miracles were called lies by the people who lived in ancient times. To the people of Thamud, We sent the she-camel as a visible miracle and they did injustice to it. We only send miracles as warnings. 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
