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 Sustainer is fully aware of what you are [and what you deserve]: if He so wills, he will bestow [His] grace upon you; and if He so wills, He will chastise you. Hence, We have not sent thee [unto men, O Prophet,] with the power to determine their fate, 54 Your Lord knows whoever is in the heavens and the earth. We exalted some of the prophets over the others; and to David We gave the Book of Psalms. 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, they call upon are themselves seeking a means to come to their Lord, competing with each other to be nearer; they hope for His Mercy and fear His punishment. Indeed, the punishment of your Lord is the subject of caution. 57 And there is not a town (population) but We shall destroy it before the Day of Resurrection, or punish it with a severe torment. That is written in the Book (of our Decrees) 58 And We refrain from sending the signs, only because the men of former generations treated them as false: We sent the she-camel to the Thamud to open their eyes, but they treated her wrongfully: We only send the Signs by way of terror (and warning from evil). 59 And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra') but a trial for mankind, and likewise the accursed tree (Zaqqum, mentioned) in the Quran. We warn and make them afraid but it only increases them in naught save great disbelief, oppression and disobedience to Allah. 60
