It is He Who subjected the earth for you, therefore tread its paths and eat from Allah’s sustenance; and towards Him is the resurrection. 15 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 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 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 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 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: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 But when they will behold it proximating sad will be the countenances of those who disbelieve, and it will be said: this is that which ye have been calling for. 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 28 Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that 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
