He it is Who hath made the earth unto you subservient, so go forth in the regions thereof, and eat of His provision. And unto Him is the Resurrection. 15 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 16 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 And certainly those before them rejected (the truth), then how was My disapproval. 18 Have they, then, never beheld the birds above them, spreading their wings and drawing them in? None but the Most Gracious upholds them: for, verily, He keeps all things in His sight. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 Say (unto them, O Muhammad): He it is who gave you being, and hath assigned unto you ears and eyes and hearts. Small thanks give ye! 23 Say: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say thou, [O Prophet:] "Knowledge thereof rests with God alone; and I am only a plain warner." 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call for. 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
