It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all 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 are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 Those who went before them belied [the truth]: then how great was My rejection of them. 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the 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 dispersed you all over the earth, and to Him you will be gathered." 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 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 Prophet]: "What do you think? Whether God destroys me and those who follow me, or graces us with His mercy - is there anyone that could protect [you] deniers of the truth from grievous suffering [in the life to come]?" 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 is your opinion – if in the morning all your water were to sink into the earth, then who is such who can bring you water flowing before you?” 30
