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 Do you feel secure that He Who is in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And verily those before them denied, then (see) the manner of My wrath (with 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 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter delusion. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. 21 Who is better guided: he who walks grovelling on his face, or he who walks upright on a Straight Path? 22 Say thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 And they say, "When is this promise, if you should be truthful?" 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 thou: bethink ye if Allah destroy me and those with me; or have mercy on us, who will protect the infidels from a torment afflictive? 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: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
