It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all 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 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And certainly those before them rejected (the truth), then how was My disapproval. 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Or, who is it that shall provide for you if He withholds His provision? Yet they persist in arrogance and aversion. 21 What! is he who goes prone upon his face better guided or he who walks upright upon a straight path? 22 Say thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 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 Beneficent. In Him we believe and in Him we put our trust. And ye will soon know who it is that is in error manifest. 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
