He it is Who hath made the earth unto you subservient, so go forth in the regions thereof, and eat of His provision. And unto Him is the Resurrection. 15 Do you feel secure that He who is in heaven will not cause the earth to swallow you, the while it rocks? 16 Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning. 17 Those that were before them also cried lies; then how was My horror! 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right 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 scattered you on the earth; and it is to Him that you shall all be gathered [on the Day of Resurrection]. 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Say, "The knowledge is only with Allah, and I am only a clear 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: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
