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 [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Do you feel secure that He Who is in the heaven will not let loose upon you a storm of stones? Then shall you know what My warning is like! 17 And certainly those before them rejected (the truth), then how was My disapproval. 18 Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of everything. 19 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 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 What! is he who goes prone upon his face better guided or he who walks upright upon a straight path? 22 Say: 'It is He who produced you, and appointed for you hearing and sight and hearts; little thanks you show!' 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 And they say, "When is this promise, if you should be truthful?" 25 Say, "God knows best. I am only one who gives warning". 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 (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom? 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, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
