It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)? 16 Or have you become so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things. 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 What, is he who walks prone upon his face better guided than he who walks upright on a 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 God who has settled you on the earth and to Him you will be resurrected". 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 But when they see it drawing near, the faces of those who deny the truth will turn gloomy and they will be told, "This is what you were calling for." 27 Say: "See ye?- If Allah were to destroy me, and those with me, or if He bestows His Mercy on us,- yet who can deliver the Unbelievers from a grievous Penalty?" 28 Say, "He is the Beneficent One in whom we have faith and trust. You will soon know who is in manifest error". 29 Say, "Have you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
