He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 15 Do you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning. 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or who is he that will be an army unto you to help you instead of the Beneficent? The disbelievers are in naught but illusion. 20 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 21 Is he who goeth groping on his face more rightly guided, or he who walketh upright on a straight road? 22 (Muhammad), say, "It is God who has brought you into being and made ears, eyes, and hearts for you, but you give very little thanks". 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 They say, "When will this torment take place if what you say is true?" 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call for. 27 Say (O dear Prophet Mohammed – peace and blessings be upon him), “What is your opinion –Allah may either destroy me and those with me, or have mercy on us – so who is such that will protect the disbelievers from the painful punishment?” 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say [unto those who deny the truth]: "What do you think? If of a sudden all your water were to vanish underground, who [but God] could provide you with water from [new] unsullied springs?" 30
