It is He Who subjected the earth for you, therefore tread its paths and eat from Allah’s sustenance; and towards Him is the resurrection. 15 Do you feel secure that He Who is in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how 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 Or who is he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 23 Say, "It is God who has settled you on the earth and to Him you will be resurrected". 24 They say, "When will this torment take place if what you say is true?" 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 Then, when they see it nigh at hand, the faces of the unbelievers will be vexed, and it will be said, 'This is what you were promised.' 27 Say: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers from the painful punishment' 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
