Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. 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 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 given no man everlastingness before you. So then if you die, will they live ever after? 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 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. Assuredly I shall show you My signs; so demand not that I make haste. 37 They say, "When shall the Day of Judgment come to pass if you are true in your claim?" 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 Nay, it shall come on them all of a sudden and cause them to become confounded, so they shall not have the power to avert it, nor shall they be respited. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
