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 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 16 Or have you become unafraid of the One Who controls the heavens, that He will not send a torrent of stones upon you? So now you will realise, how My warning turned out! 17 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 Have they not regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees 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 Or who is such that will give you sustenance if Allah stops His sustenance? In fact they persist in rebellion and hatred. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right path? 22 Say: “He it is Who has brought you into being, and has given you hearing and sight, and has given you hearts to think and understand. How seldom do you give thanks!” 23 Say thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public." 26 So when they will see it close, the faces of the disbelievers will become ghastly, and it will be declared, “This is what you were demanding.” 27 SAY [O Prophet]: "What do you think? Whether God destroys me and those who follow me, or graces us with His mercy - is there anyone that could protect [you] deniers of the truth from grievous suffering [in the life to come]?" 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
