He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 15 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 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 who went before them belied [the truth]: then how great was My rejection of 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 Or, who is it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 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 (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: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 But when they see it approaching, the faces of those who disbelieve will be distressed, and it will be said, "This is that for which you used to call." 27 Say, [O Muhammad], "Have you considered: whether Allah should cause my death and those with me or have mercy upon us, who can protect the disbelievers from a painful punishment?" 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 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
