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 Do you feel secure that He Who is in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 16 Or are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 Those who went before them belied [the truth]: then how great was My rejection of them. 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 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 who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. 21 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 SAY: "[God is] He who has brought you [all] into being, and has endowed you with hearing, and sight, and hearts: [yet] how seldom are you grateful!" 23 Say, "It is He who has scattered you on the earth; and it is to Him that you shall all be gathered [on the Day of Resurrection]. 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 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 (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom? 28 Say, "He is the Beneficent One in whom we have faith and trust. You will soon know 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
