Say (unto the disbelievers): Travel in the land, and see the nature of the consequence for the rejecters! 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 ۞ His is whatever is at rest in the night and in the day. He is the Hearing, the Knowing. 13 Say: 'Shall I take for my guardian anyone other than Allah - the Originator of the heavens and earth; He Who feeds and Himself is not fed?' Say: 'Surely I have been commanded to be the first among those who submit (to Allah) and not to be one of those who associate others with Allah in His divinity (even though others may do so).' 14 Say: "If I disobey my Lord, I fear the punishment of a grievous Day." 15 Who is averted from (such a torment) on that Day, (Allah) has surely been Merciful to him. And that would be the obvious success. 16 If God sends you harm, there is no one but He who can take it away; and if He bring you good, surely He has power over everything. 17 He is the Omnipotent over His bondmen; and He is the Wise, the Aware. 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
