It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the resurrection. 15 Do you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Do you feel secure that He who is in heaven will not loose against you a squall of pebbles, then you shall know how My warning is? 17 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right 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 thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 But when they will see it (the torment on the Day of Resurrection) approaching, the faces of those who disbelieve will be different (black, sad, and in grieve), and it will be said (to them): "This is (the promise) which you were calling for!" 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 All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, know who 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
