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 We set firm mountains upon the earth lest it should shake with them, and We placed therein ravines to be paths so that they might be guided. 31 We have made the heaven a well-secured canopy; yet still they turn away from Our signs. 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 before you, We did not appoint on earth a never-ending life for any human; will they, if you depart, become immortal? 34 Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned. 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 was created of haste. I will show you My signs, so do not impatiently urge Me. 37 And they say: "When will this promise (come to pass), if you are truthful." 38 If the unbelievers but knew when that they shall not ward off the Fire from their faces nor from their backs, neither 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 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
