He it is Who hath made the earth unto you subservient, so go forth in the regions thereof, and eat of His provision. And unto Him is the Resurrection. 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 have gone before you also belied (their Messengers) then how was My disapproval! 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 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 can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 21 Is he who walks grovelling upon his face better guided, or he who walks upright upon a straight path? 22 Say (unto them, O Muhammad): He it is who gave you being, and hath assigned unto you ears and eyes and hearts. Small thanks give ye! 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say thou, [O Prophet:] "Knowledge thereof rests with God alone; and I am only a plain warner." 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked for." 27 Say: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers from the painful punishment' 28 Say, "He is the Most Gracious: we believe in Him and we put our trust in Him. You will soon come to know who is in evident error." 29 Say: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
