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 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 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 [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 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 walks, falling upon his face, more guided than he who walks upright on a Straight Path! 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 And they say, "When is this promise, if you should be truthful?" 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 Then, when they see it nigh at hand, the faces of the unbelievers will be vexed, and it will be said, 'This is what you were promised.' 27 Say: "Just think: If God destroys me and those with me, or is benevolent to us, who will then protect the unbelievers from a painful doom?" 28 Say: He is the Beneficent Allah, we believe in Him and on Him do we rely, so you shall come to know who it is that is in clear 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
