He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 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 the heaven will not let loose upon you a storm of stones? Then shall you know what My warning is like! 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 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 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 SAY: "[God is] He who has brought you [all] into being, and has endowed you with hearing, and sight, and hearts: [yet] how seldom are you grateful!" 23 Say, “It is He Who has spread you out in the earth, and towards Him you will be raised.” 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 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 to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest error.” 29 Say: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
