Have not the unbelievers then beheld that the heavens and the earth were a mass all sewn up, and then We unstitched them and of water fashioned every living thing? Will they not believe? 30 And We have placed in the earth firm mountains lest it should move away with them, and We placed therein passages for paths, that haply they may be guided. 31 And We have made the heaven a guarded canopy and (yet) they turn aside from its signs. 32 It is He who created night and day, the sun and the moon, revolving on its orbit. 33 We have not granted everlasting life to any human being before you; then if you [Muhammad] should die, will they live forever? 34 Every living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to return. 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: 'If you are truthful, when will this promise come' 38 If the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not 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 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
