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 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 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 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Do they not see the birds above them with wings outspread and [sometimes] folded in? None holds them [aloft] except the Most Merciful. Indeed He is, of all things, Seeing. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 21 What, is he who walks, falling upon his face, more guided than he who walks upright on a Straight Path! 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 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: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public." 26 When they see the torment approaching, the faces of the disbelievers will blacken and they will be told, "This is what you wanted to (experience)". 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 Beneficent Allah, we believe in Him and on Him do we rely, so you shall come to know who it is that is in clear 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
