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 you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 16 Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a violent whirlwind? Then you shall know how (terrible) has been My Warning? 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 18 Do they not see the birds above them flying wings spread out or folded? Nothing holds them aloft but God. All things are within His purview. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]! 21 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 Proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “It is He Who created you, and made ears and eyes and hearts for you; very little thanks do you offer!” 23 Say: "It is He who dispersed you all over the earth, and to Him you will be gathered." 24 And they say, “When will this promise come, if you are truthful?” 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 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, "Have you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
