It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 15 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 16 Or have ye taken security from Him Who is in the heaven that He will not let loose on you a hurricane? But ye shall know the manner of My warning. 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Do they not see the birds above them flying wings spread out or folded? Nothing holds them aloft but God. All things are within His purview. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? 22 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 But when they will behold it proximating sad will be the countenances of those who disbelieve, and it will be said: this is that which ye have been calling 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 Say to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest error.” 29 Say: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
