He it is Who hath made the earth subservient unto you, so Walk in the paths thereof and eat of His providence. And unto Him will be the resurrection (of the dead). 15 Are you so unafraid that He who is in Heaven will not open up the earth to swallow you, when it will begin to tremble? 16 Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a violent whirlwind? Then you shall know how (terrible) has been My Warning? 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of everything. 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 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: "It is He who dispersed you all over the earth, and to Him you will be gathered." 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 Yet in the end, when they shall see that [fulfilment] close at hand, the faces of those who were bent on denying the truth will be stricken with grief; and they will be told, "This it is that you were [so derisively] 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 (Allah) Most Gracious: We have believed in Him, and on Him have we put our trust: So, soon will ye know which (of us) it is that is in manifest error." 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
