He it is, Who has made the earth subservient to you (i.e. easy for you to walk, to live and to do agriculture on it, etc.), so walk in the path thereof and eat of His provision, and to Him will be the Resurrection. 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 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 And indeed those before them had denied – therefore how did My rejection turn out! 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! 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 thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say: "It is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say: The knowledge (thereof is only with Allah and I am only a plain warner. 26 Yet in the end, when they shall see that [fulfilment] close at hand, the faces of those who were bent on denying the truth will be stricken with grief; and they will be told, "This it is that you were [so derisively] calling for!" 27 Say: "See ye?- If Allah were to destroy me, and those with me, or if He bestows His Mercy on us,- yet who can deliver the Unbelievers from a grievous Penalty?" 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
