It is He who made the earth subservient to you that you may travel all around it, and eat of things He has provided; and to Him will be your resurrection. 15 Do you feel secure that He who is in heaven will not cause the earth to swallow you, the while it rocks? 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 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over 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 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 given to you hearing, sight and hearts but little is it that you thank' 23 Say: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 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: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 28 Say thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 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
