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 Do you feel secure that He who is in heaven will not cause the earth to swallow you, the while it rocks? 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 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Who is he that can provide for you, should He withhold His provision? Aye! they persists in perverseness and aversion. 21 Is he who goeth groping on his face more rightly guided, or he who walketh upright on a straight road? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 But when they will see it (the torment on the Day of Resurrection) approaching, the faces of those who disbelieve will be different (black, sad, and in grieve), and it will be said (to them): "This is (the promise) which you 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 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
