He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 15 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 19 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter delusion. 20 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 21 Who is better guided: he who walks grovelling on his face, or he who walks upright on a Straight Path? 22 Proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “It is He Who created you, and made ears and eyes and hearts for you; very little thanks do you offer!” 23 Say: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye were calling 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 One in whom we have faith and trust. You will soon know who is in manifest error". 29 Say: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
