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 you feel secure that the One in the heavens will not cause you to sink into the earth when it is violently shaking? 16 Or are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Who is there to give you food in case He withholds His bounty? Yet they persist in rebellion and aversion. 21 What, is he who walks, falling upon his face, more guided than he who walks upright on a Straight Path! 22 Say thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 They say, "When will this torment take place if what you say is true?" 25 Say: 'The knowledge is with God; I am only a clear 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 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 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 to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
