It is He who has made the earth subservient to you, so traverse its regions and eat its provisions. To Him you shall all be resurrected. 15 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 16 Do you feel secure that He who is in heaven will not loose against you a squall of pebbles, then you shall know how My warning is? 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees 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 he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness. 21 What! is he who goes prone upon his face better guided or he who walks upright upon a straight path? 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 God who has settled you on the earth and to Him you will be resurrected". 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked for." 27 Say to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous chastisement?” 28 Say, "He is the Most Gracious: we believe in Him and we put our trust in Him. You will soon come to know who is in evident error." 29 Say thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
