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 Have you become unafraid of the One Who controls the heavens, that He will not cause you to sink into the earth when it trembles? 16 Do you feel secure that the One in heaven will not send against you a whirlwind to pelt you with stones, so that you will know how [true] My warning was? 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 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 it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 20 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 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 say sooth? 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 Then, when they see it drawing near, the faces of the unbelievers will be blackened, and it is said: 'This is what you were promised' 27 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 28 Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say (O Muhammad SAW): "Tell me! If (all) your water were to be sunk away, who then can supply you with flowing (spring) water?" 30
