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 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 16 Do you feel secure that He who is in the heaven will not loose against you a squall of pebbles then you shall know how was My warning. 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 18 Have they not regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees everything. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 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 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say, "It is God who has settled you on the earth and to Him you will be resurrected". 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public." 26 But when they will see it (the torment on the Day of Resurrection) approaching, the faces of those who disbelieve will be different (black, sad, and in grieve), and it will be said (to them): "This is (the promise) which you were calling for!" 27 Say, [O Muhammad], "Have you considered: whether Allah should cause my death and those with me or have mercy upon us, who can protect the disbelievers from a 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: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
