He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you 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 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 expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 19 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the Straight Path? 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: "It is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say, "God knows best. I am only one who gives 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: "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 All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, know who 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
