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 [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 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 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 the birds above them spreading out their wings and closing them? Naught upholdeth them save the Beneficent. Lo! He is Seer of all things. 19 Who is he besides the Most Beneficent that can be an army to you to help you? The disbelievers are in nothing but delusion. 20 Who is there to give you food in case He withholds His bounty? Yet they persist in rebellion and aversion. 21 What, is he who walks, falling upon his face, more guided than he who walks upright on a Straight Path! 22 Proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “It is He Who created you, and made ears and eyes and hearts for you; very little thanks do you offer!” 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 Then, when they see it drawing near, the faces of the unbelievers will be blackened, and it is said: 'This is what you were promised' 27 Say: "Just think: If God destroys me and those with me, or is benevolent to us, who will then protect the unbelievers from a painful doom?" 28 Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
