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 Are you so unafraid that He who is in Heaven will not open up the earth to swallow you, when it will begin to tremble? 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 Those that were before them also cried lies; then how was My horror! 18 Do they not see the birds above them with wings outspread and [sometimes] folded in? None holds them [aloft] except the Most Merciful. Indeed He is, of all things, Seeing. 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 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of 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: "It is He who raised you and gave you ears and eyes and hearts. How little are the thanks you offer!" 23 Say thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say: “Allah alone knows about that; and I am no more than a plain 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: 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 to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
