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 in heaven will not cause the earth to swallow you, the while it rocks? 16 Do you feel secure that the One in heaven will not send against you a whirlwind to pelt you with stones, so that you will know how [true] My warning was? 17 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or, who is it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 20 Who is he that can provide for you, should He withhold His provision? Aye! they persists in perverseness and aversion. 21 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 22 Say: "It is He who raised you and gave you ears and eyes and hearts. How little are the thanks you offer!" 23 Say, "It is God who has settled you on the earth and to Him you will be resurrected". 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 Then, when they see it drawing near, the faces of the unbelievers will be blackened, and it is said: 'This is what you were promised' 27 Say, "Have you thought: if God destroys me and those who are with me, or treats us mercifully, then who will protect those who deny the truth from a painful chastisement?" 28 Say: "He is the benevolent; in Him do we believe, and in Him do we place our trust. You will now realise 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
