It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Have you become unafraid of the One Who controls the heavens, that He will not cause you to sink into the earth when it trembles? 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 already had those before them denied, and how [terrible] was My reproach. 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Or, who is it that shall provide for you if He withholds His provision? Yet they persist in arrogance and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say (unto them, O Muhammad): He it is who gave you being, and hath assigned unto you ears and eyes and hearts. Small thanks give ye! 23 Say: "It is He Who has multiplied you through the earth, and to Him shall ye be gathered together." 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 Then, when they see it nigh at hand, the faces of the unbelievers will be vexed, and it will be said, 'This is what you were promised.' 27 SAY [O Prophet]: "What do you think? Whether God destroys me and those who follow me, or graces us with His mercy - is there anyone that could protect [you] deniers of the truth from grievous suffering [in the life to come]?" 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: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
