Have the unbelievers not seen that the heavens and the earth were sewn up as one (solid) mass, then We unstitched them, and that We made every living thing of water? 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 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 And He it is Who created the night and the day and the sun and the moon; all (orbs) travel along swiftly in their celestial spheres. 33 And We did not grant to any man before you eternity [on earth]; so if you die - would they be eternal? 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 is created of haste; now will I show to you My signs, therefore do not ask Me to hasten (them) on. 37 And they say, "When is this promise, if you should be truthful?" 38 Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor shall they be helped. 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 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41
