Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? 30 And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided. 31 and We set up the heaven as a roof well-protected; yet still from Our signs they are turning away. 32 And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming. 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 a creature of haste. Soon I will show you My signs, but do not ask Me to hasten them. 37 And they say: "When will this promise (come to pass), if you are truthful." 38 If only those who disbelieved knew (the time) when they will not be able to ward off the Fire from their faces, nor from their backs; and they will not be helped. 39 Indeed, it will come upon them suddenly and confound them; and they will not be able to ward it off, nor shall they be reprieved. 40 Other messengers have been mocked before you, but those who scoffed were overwhelmed by the very thing they had mocked. 41
