Do not these unbelievers see that the heavens and the earth were an integrated mass, then We split them and made every living thing from water? Will they not believe even then? 30 And We set in the earth firm mountains lest it should shake with them, and We set in it ravines to serve as ways, that haply so they may be guided; 31 We have made the heaven a well-secured canopy; yet still they turn away from Our signs. 32 And He it is Who has created the night and the day, and the sun and the moon, each in an orbit floating. 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 living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to return. 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 The human being is created hasty. Tell them, "Do not be hasty, for God will soon show you the evidence of His existence". 37 And they say: When will this threat come to pass if you are truthful? 38 If they but knew - they who are bent on denying the truth - [that there will come] a time when they will not be able to ward off the fire from their faces, nor from their backs, and will not find any succour! 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any respite. 40 Many apostles have been scoffed before you; but they who scoffed were themselves caught by what they had ridiculed. 41
