He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 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 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 Those before them had also denied. And how was My punishment then! 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only 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 SAY: "[God is] He who has brought you [all] into being, and has endowed you with hearing, and sight, and hearts: [yet] how seldom 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 say, 'When shall this promise come to pass, if you speak truly?' 25 Say: 'The knowledge is with God; I am only a clear warner.' 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call for. 27 Say (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom? 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
