Say: 'Go about journeying the earth, and behold the end of those who gave the lie (to the Truth).' 11 Say, “To Whom does all whatever is in the heavens and the earth, belong?” Proclaim, “To Allah”; He has made mercy obligatory upon His grace; undoubtedly, He will surely gather you all together on the Day of Resurrection in which there is no doubt; those who put their souls to ruin, do not accept faith. 12 ۞ To Him belongs all that rests during the night and the day. He is All-hearing and All-knowing." 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, "I will never disobey my Lord, for I fear the punishment of a dreadful 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 Allah touches you with harm, none can remove it but He, and if He touches you with good, then He is Able to do all things. 17 And He is the subjugator over His servants. And He is the Wise, the Acquainted [with all]. 18 Say, "What thing is greatest in testimony?" Say, "Allah is witness between me and you. And this Qur'an was revealed to me that I may warn you thereby and whomever it reaches. Do you [truly] testify that with Allah there are other deities?" Say, "I will not testify [with you]." Say, "Indeed, He is but one God, and indeed, I am free of what you associate [with Him]." 19 Those to whom We have given the Book know this as they know their own sons. Those who have lost their own souls refuse therefore to believe. 20
