He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you 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 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 And certainly those before them rejected (the truth), 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 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter 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 Who is better guided: he who walks grovelling on his face, or he who walks upright 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 is He who scattered you in the earth, and unto Him you shall be mustered.' 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: “Allah alone knows about that; and I am no more than 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, [O Muhammad], "Have you considered: whether Allah should cause my death and those with me or have mercy upon us, who can protect the disbelievers from a painful punishment?" 28 Say: "He is the benevolent; in Him do we believe, and in Him do we place our trust. You will now realise who is in manifest error." 29 Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?" 30
