It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Have you become unafraid of the One Who controls the heavens, that He will not cause you to sink into the earth when it trembles? 16 Or have you become so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 19 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right path? 22 Say thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will 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, "The knowledge is only with Allah, and I am only a clear warner." 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 (O dear Prophet Mohammed – peace and blessings be upon him), “What is your opinion –Allah may either destroy me and those with me, or have mercy on us – so who is such that will protect the disbelievers from the painful punishment?” 28 Say: "He is the Most Gracious: we have attained to faith in Him, and in Him have we placed our trust; and in time you will come to know which of us was lost in manifest error." 29 Say to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
