It is He Who has made the earth manageable for you, so traverse ye through its tracts and enjoy of the Sustenance which He furnishes: but unto Him is the Resurrection. 15 Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)? 16 Or have you become unafraid of the One Who controls the heavens, that He will not send a torrent of stones upon you? So now you will realise, how My warning turned out! 17 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Do they not see the birds above them with wings outspread and [sometimes] folded in? None holds them [aloft] except the Most Merciful. Indeed He is, of all things, Seeing. 19 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter 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, falling upon his face, more guided than he who walks upright 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 was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 Then, when they see it nigh at hand, the faces of the unbelievers will be vexed, and it will be said, 'This is what you were promised.' 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 benevolent; in Him do we believe, and in Him do we place our trust. You will now realise who is in manifest error." 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
