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 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 Those who have gone before you also belied (their Messengers) then how was My disapproval! 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? 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 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 21 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say (O Muhammad SAW): "The knowledge (of its exact time) is with Allah only, and I am only a plain warner." 26 But when they see it drawing near, the faces of those who deny the truth will turn gloomy and they will be told, "This is what you were calling for." 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 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 thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
