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 the One in the heavens will not cause you to sink into the earth when it is violently shaking? 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 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 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 [And] is there any, besides the Most Gracious, that could be a shield for you, and could succour you [against danger]? They who deny this truth are but lost in self-delusion! 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 Then is one who walks fallen on his face better guided or one who walks erect 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: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Say thou, [O Prophet:] "Knowledge thereof rests with God alone; and I am only a plain warner." 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: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful 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: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
