Say: 'Journey in the land, then behold how was the end of them that cried lies.' 11 Ask them, "Who is the owner of the heavens and the earth besides God, the All-merciful, who will gather you all together on the Day of Judgment? That day will certainly come. Those who have lost their souls will not believe. 12 ۞ To him belongeth all that dwelleth (or lurketh) in the night and the day. For he is the one who heareth and knoweth all things." 13 Say, "Is it other than Allah I should take as a protector, Creator of the heavens and the earth, while it is He who feeds and is not fed?" Say, [O Muhammad], "Indeed, I have been commanded to be the first [among you] who submit [to Allah] and [was commanded], 'Do not ever be of the polytheists.' " 14 Say: "If I disobey my Lord, I fear the punishment of a grievous Day." 15 "On that day, if the penalty is averted from any, it is due to Allah's mercy; And that would be (Salvation), the obvious fulfilment of all desire. 16 And if Allah afflicts you with some misfortune, then there is none who can remove it, except Him; and if He sends you some good fortune, then (know that) He is Able to do all things. 17 He is Omnipotent over His servants, and He is the All-wise, the All-aware. Say: 'What thing is greatest in testimony?' 18 Ask: "Of all things what is most vital as evidence?" Say: "God (who) is witness between you and me that this Qur'an has been revealed to me that I may warn you on its strength, and those whom it reaches. Do you really bear witness there are other gods with God?" Tell them: "I bear no such Witness." Say: "Verily He is the only God, and I am clear of what you associate (with Him)." 19 Those whom We have given the Book will recognize this just as they recognize their own ofspring; but those who have courted their own ruin will not believe. 20
