He it is Who hath made the earth unto you subservient, so go forth in the regions thereof, and eat of His provision. And unto Him is the Resurrection. 15 Do you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning. 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of everything. 19 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say thou: the knowledge is only with Allah, and I am but a warner manifest. 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 (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 to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest error.” 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
