It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 15 Do you feel secure that He who is in heaven will not cause the earth to sink beneath you and then begin to quake? 16 Do you feel secure that He who is in the heaven will not loose against you a squall of pebbles then you shall know how was My warning. 17 And already had those before them denied, and how [terrible] was My reproach. 18 Have they, then, never beheld the birds above them, spreading their wings and drawing them in? None but the Most Gracious upholds them: for, verily, He keeps all things in His sight. 19 Or, who is it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Is he who walks without seeing on his face, more rightly guided, or he who (sees and) walks on a Straight Way (i.e. Islamic Monotheism). 22 Say: "It is He Who has created you (and made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give. 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 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 But when they see it approaching, the faces of those who disbelieve will be distressed, and it will be said, "This is that for which you used to call." 27 Say to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous chastisement?” 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is 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
