It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the resurrection. 15 Do you feel secure that He Who is in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 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 who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Or, who is it that shall provide for you if He withholds His provision? Yet they persist in arrogance and aversion. 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 (Muhammad), say, "It is God who has brought you into being and made ears, eyes, and hearts for you, but you give very little thanks". 23 Say: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say, "God knows best. I am only one who gives warning". 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 to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous chastisement?” 28 Say thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
