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 on the earth firm mountains, lest it should shake with them, and We placed therein broad highways for them to pass through, that they may be guided. 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 32 And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit. 33 And We did not ordain abiding for any mortal before you. What! Then if you die, will they abide? 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 When those who deny the truth see you, they laugh at you, saying, "Is this the one who talks of your deities?" Yet it is they who deny all mention of the Gracious One. 36 Man is a creature of haste; [but in time] I shall make obvious to you [the truth of] My messages: do not, then, ask Me to hasten [it]! 37 And they say: When will this promise (be fulfilled), if ye are truthful? 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 Nay, it may come to them all of a sudden and confound them: no power will they have then to avert it, nor will they (then) get respite. 40 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41
