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 in heaven will not cause the earth to sink beneath you and then begin to quake? 16 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of everything. 19 Or who is he that will be an army unto you to help you instead of the Beneficent? The disbelievers are in naught but illusion. 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 has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 And they say, "When is this promise, if you should be truthful?" 25 Say: 'The knowledge is with God; 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 (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom? 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 (O Muhammad SAW): "Tell me! If (all) your water were to be sunk away, who then can supply you with flowing (spring) water?" 30
