It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 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 so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Who is he that can provide for you, should He withhold His provision? Aye! they persists in perverseness and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say: "It is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call 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, "He is the Beneficent One in whom we have faith and trust. You will soon know who is in manifest error". 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
