Say: "Travel through the earth and see what was the end of those who rejected Truth." 11 Say: "To whom belongeth all that is in the heavens and on earth?" Say: "To Allah. He hath inscribed for Himself (the rule of) Mercy. That He will gather you together for the Day of Judgment, there is no doubt whatever. It is they who have lost their own souls, that will not believe. 12 ۞ His is whatsoever dwelleth in the night and the day; and He is the Hearer, the Knower. 13 Say, "Shall I take as my protector someone other than God, Creator of the heavens and the earth, who feeds all and is fed by none?" Say, "I have been commanded to be the first of those who submit. Do not be one of the polytheists." 14 Say, “If I disobey my Lord, I then fear the punishment of the Great Day (of Resurrection).” 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 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 Irresistible, above His slaves, and He is the All-Wise, Well-Acquainted with all things. 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 unto whom We gave the Scripture recognise (this revelation) as they recognise their sons. Those who ruin their own souls will not believe. 20
