He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you be resurrected. 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 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 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 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 [And] is there any, besides the Most Gracious, that could be a shield for you, and could succour you [against danger]? They who deny this truth are but lost in self-delusion! 20 Or who is such that will give you sustenance if Allah stops His sustenance? In fact they persist in rebellion and hatred. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right path? 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 He who dispersed you all over the earth, and to Him you will be gathered." 24 They ask: 'When will this promise come, if you speak truthfully' 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 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, "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 Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
