Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided. 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 32 And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming. 33 And We appointed not for any human being before thee immortality; if thou then diest, are they to be immortals? 34 Every living being shall taste death and We shall subject you to ill and good by way of trial, and to Us shall all of you be eventually sent back. 35 And when the disbelievers see you, they do not appoint you except as an object of mockery; “Is he the one who speaks ill of your Gods?”; whereas they deny the remembrance of the Most Gracious Himself! 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 37 And they say: When will this promise (be fulfilled), if ye are truthful? 38 If only the disbelievers realised the time when they will not be able to stop the fire from their faces and from their backs – and nor are they to be helped. 39 In fact it will suddenly come upon them, therefore shocking them, and they will not be able to repel it nor will they be given respite. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
