Say: Travel in the land, then see what was the end of the rejecters. 11 Say, "To whom belongs whatever is in the heavens and earth?" Say, "To Allah." He has decreed upon Himself mercy. He will surely assemble you for the Day of Resurrection, about which there is no doubt. Those who will lose themselves [that Day] do not believe. 12 ۞ Unto Him belongeth whatsoever resteth in the night and the day. He is the Hearer, the Knower. 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: "I fear, if I disobey my Lord, the torment of a Mighty Day." 15 He from whom (such retribution) is averted on that day, (Allah) hath in truth had mercy on him. That will be the signal triumph. 16 And if God visits thee with affliction none can remove it but He; and if He visits thee with good, He is powerful over everything. 17 for He alone holds sway over His creatures, and He alone is truly wise, all-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 The People of the Book know him (Muhammad) just as well as they know their own children, but those who have lost their souls will not believe. 20
