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 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 16 Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning. 17 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 Have they not seen the birds above them spreading out their wings and closing them? Naught upholdeth them save the Beneficent. Lo! He is Seer of all things. 19 Who is he besides the Most Beneficent that can be an army to you to help you? The disbelievers are in nothing but delusion. 20 Who shall provide for you if He withholds His sustenance? Nay; but 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 (unto them, O Muhammad): He it is who gave you being, and hath assigned unto you ears and eyes and hearts. Small thanks give ye! 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say: 'The knowledge (of that) is with Allah; 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: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers from the painful punishment' 28 Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
