He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you be resurrected. 15 Do you feel secure that He who is in heaven will not cause the earth to sink beneath you and then begin to quake? 16 Do you feel secure that He who is in heaven will not loose against you a squall of pebbles, then you shall know how My warning is? 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 Or who is he that will be an army unto you to help you instead of the Beneficent? The disbelievers are in naught but illusion. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 (Muhammad), say, "It is God who has brought you into being and made ears, eyes, and hearts for you, but you give very little thanks". 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 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. In Him we believe and in Him we put our trust. And ye will soon know who it is that is in error manifest. 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
