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 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 Those who went before them belied [the truth]: then how great was My rejection of them. 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 it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 Is he who walks without seeing on his face, more rightly guided, or he who (sees and) walks on a Straight Way (i.e. Islamic Monotheism). 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 through the earth, and to Him shall ye be gathered together." 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 When they see the torment approaching, the faces of the disbelievers will blacken and they will be told, "This is what you wanted to (experience)". 27 Say, "Have you thought: if God destroys me and those who are with me, or treats us mercifully, then who will protect those who deny the truth from a painful chastisement?" 28 Say: 'He is the All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, know who is in manifest error. 29 Say thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
