It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the resurrection. 15 Do you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning. 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in 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 Is he who walks grovelling upon his face better guided, or he who walks upright upon a straight path? 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 scattered you in the earth, and unto Him you shall be mustered.' 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 But when they will behold it proximating sad will be the countenances of those who disbelieve, and it will be said: this is that which ye have been calling for. 27 Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment? 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
