Say: 'Journey in the land, then behold how was the end of them that cried lies.' 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 ۞ And to Him only belongs all whatever exists in the night and in the day; and He only is the All Hearing, the All Knowing. 13 Say thou: Shall I take for a patron any other than Allah, the Maker of the heavens and the earth! And He feedeth, and is not fed. Say thou: I am commanded that I be the first who submitteth himself, and that: be thou not of the associaters. 14 Say: 'Indeed I fear, if I should rebel against thy Lord, the chastisement of a dreadful day.' 15 From whomsoever it is averted on that day, He will have mercy on him; that is the manifest triumph. 16 If Allah touch thee with hurt there is no reverser thereof but He, and if He touch thee with good, then He is over everything Potent. 17 And He is the Supreme, above His servants; 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 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
