It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 16 Or have you become unafraid of the One Who controls the heavens, that He will not send a torrent of stones upon you? So now you will realise, how My warning turned out! 17 And already had those before them denied, and how [terrible] was My reproach. 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 Do you have any armies who will help you against the Beneficent God? The disbelievers are certainly deceived (by satan). 20 Who is there to give you food in case He withholds His bounty? Yet they persist in rebellion and aversion. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye 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 thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
