Have not these who disbelieve considered that the heavens and the earth were closed up, then We rent them? And We have made of water everything living; will they not then 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 heaven a roof, safe, and from the signs thereof they are averters. 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 And We granted not to any human being immortality before you (O Muhammad SAW), then if you die, would they live forever? 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 is hasty by nature. I shall certainly show you My Signs. Do not ask Me to be hasty. 37 And they say: When will this promise (be fulfilled), if ye are truthful? 38 If those who disbelieved but knew the time when they will not be able to drive off the fire from their faces and from their backs, and they will not be helped! 39 It will come upon them unawares confounding them, and they will not be able to keep it back, nor will they be given respite. 40 And indeed, [O Muhammad, even] before thy time have [God's] apostles been derided - but those who scoffed at them were [in the end] overwhelmed by the very thing which they had been wont to deride. 41
