Do not those who deny the truth see that the heavens and the earth were joined together and that We then split them asunder? And that We have made every living thing out of water? Will they still not believe? 30 We set firm mountains upon the earth lest it should sway under them, and We placed therein passages for paths so that they might find their way. 31 And We have made the heaven a roof, safe and well guarded. Yet they turn away from its signs (i.e. sun, moon, winds, clouds, etc.). 32 It is He who created the night and the day, the sun and the moon, each swimming in a sky. 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 34 Every soul has to experience the taste of death. We test you with both hardships and blessings. In the end you will all return to Us. 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 is hasty by nature. I shall certainly show you My Signs. Do not ask Me to be hasty. 37 They ask, "When will this promise be fulfilled, if what you say be true?" 38 If those who disbelieved but knew the time when they will not avert the Fire from their faces or from their backs and they will not be aided... 39 Nay, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
