Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe? 30 And We placed firm mountains on earth lest it should sway with them, and We made wide paths in them that they may find their way; 31 And We have made the sky a roof, protected; and they turn away from its signs. 32 It is He who created the night and the day, and the sun and the moon, each gliding in its orbit. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 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. I will show you My signs, so do not impatiently urge Me. 37 They ask, "When will this promise be fulfilled, if what you say be true?" 38 If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them! 39 It will overtake them suddenly, dumbfounding them. They shall be unable to ward it off, and they shall not be respited. 40 And assuredly mocked were the apostles before thee, then there surrounded those of them who scoffed that whereat they had been mocking! 41
