It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 15 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 16 Do you feel secure that He who is in the heaven will not loose against you a squall of pebbles then you shall know how was My warning. 17 Those before them had also denied. And how was My punishment then! 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 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 has created you (and made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give. 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 26 When they will see it near at hand, the faces of all those who had denied it will be distraught, and then they will be told: “This is the doom which you used to ask 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 to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest error.” 29 Say: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
