It is He who has made the earth submissive to you. Walk about in its land and eat of His provision. To Him is the Resurrection. 15 Do you feel secure that the One in the heavens will not cause you to sink into the earth when it is violently shaking? 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 Those before them had also denied. And how was My punishment then! 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Or who is such that will give you sustenance if Allah stops His sustenance? In fact they persist in rebellion and hatred. 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, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 They say: "When will this promise (i.e. the Day of Resurrection) come to pass? if you are telling the truth." 25 Say: 'The knowledge is with God; I am only a clear warner.' 26 Then, when they see it drawing near, the faces of the unbelievers will be blackened, and it is said: 'This is what you were promised' 27 Say to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous 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 (O Muhammad SAW): "Tell me! If (all) your water were to be sunk away, who then can supply you with flowing (spring) water?" 30
