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 Do you feel secure that He who is in the heaven will not cause the earth to swallow you up while it shakes? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And already had those before them denied, and how [terrible] was My reproach. 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 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter delusion. 20 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say, "The knowledge is only with Allah, and I am only a clear 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 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say, “What is your opinion – if in the morning all your water were to sink into the earth, then who is such who can bring you water flowing before you?” 30
