It is He Who subjected the earth for you, therefore tread its paths and eat from Allah’s sustenance; and towards Him is the resurrection. 15 Do you feel secure that He who is in the heaven will not cause the earth to swallow you up while it shakes? 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 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 19 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter delusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 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 given to you hearing, sight and hearts but little is it that you thank' 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 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 When they see the torment approaching, the faces of the disbelievers will blacken and they will be told, "This is what you wanted to (experience)". 27 Say: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers from the painful punishment' 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 thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
