He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 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 have you become unafraid of the One Who controls the heavens, that He will not send a torrent of stones upon you? So now you will realise, how My warning turned out! 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 21 What, is he who walks, falling upon his face, more guided than he who walks upright on 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 thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye were calling for!" 27 Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment? 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
