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 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 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 certainly those before them rejected (the truth), then how was My disapproval. 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 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Who is he that can provide for you, should He withhold His provision? Aye! they persists in perverseness and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 And they say, “When will this promise come, if you are truthful?” 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: "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 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 you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
