Say: 'Journey in the land, then behold how was the end of them that cried lies.' 11 And ask: "To whom belongs what is in the heavens and the earth?" Say: "To God." He has prescribed grace for Himself. He will gather you on the Day of Resurrection which is certain to come. Only they who are lost of soul will not come to 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: 'Shall I take to myself as protector other than God, the Originator of the heavens and of the earth, He. who feeds and is not fed?' Say: 'I have been commanded to be the first of them that surrender: "Be not thou of the idolaters."' 14 Say: 'Indeed I fear, if I should rebel against thy Lord, the chastisement of a dreadful day.' 15 "On that day, if the penalty is averted from any, it is due to Allah's mercy; And that would be (Salvation), the obvious fulfilment of all desire. 16 (Muhammad), if God afflicts you with hardship, no one besides Him will be able to relieve you. If He bestows a favor on you, know that He has power over all things. 17 He is the Omnipotent over His slaves, and He is the Wise, the Knower. 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 Scriptures know this as they know their own sons. But those who have ruined their souls will not believe. 20
