Do not these unbelievers see that the heavens and the earth were an integrated mass, then We split them and made every living thing from water? Will they not believe even then? 30 We placed stabilisers in the earth so that as it revolved with them you lived undisturbed; and We provided passageways between them so that men may find their way; 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 34 Every soul must taste of death and We try you by evil and good by way of probation; and to Us you shall be brought back. 35 And when those who disbelieve (in the Oneness of Allah) see you (O Muhammad SAW), they take you not except for mockery (saying): "Is this the one who talks (badly) about your gods?" While they disbelieve at the mention of the Most Beneficent (Allah). [Tafsir. Al-Qurtubi]. 36 Man was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 They say, 'And when shall the promise come to pass, if you speak truly?' 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 Aye! it would come upon them on a sudden and shall dumbfound them; they shall not be able to avert it, nor shall they be respited. 40 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41
