But as for him who is given his Book behind his back (he who has turned his back to the Book, looking back to the ancestral traditions),
فَسَوْفَ يَدْعُو ثُبُورًا ( 11 )
He will be inviting upon himself chaos.
وَيَصْلَىٰ سَعِيرًا ( 12 )
And enter the Blazing Flame.
إِنَّهُ كَانَ فِي أَهْلِهِ مَسْرُورًا ( 13 )
Behold, he used to enjoy the company of his own kind.
إِنَّهُ ظَنَّ أَن لَّن يَحُورَ ( 14 )
For, behold, he deemed that life would never quit revolving like this.
بَلَىٰ إِنَّ رَبَّهُ كَانَ بِهِ بَصِيرًا ( 15 )
Nay, but behold, his Lord did see all his mettle. ('Bihi' = In him = His true worth = His mettle).
فَلَا أُقْسِمُ بِالشَّفَقِ ( 16 )
Oh, I call to witness the Rosy Afterglow of sunset.
وَاللَّيْلِ وَمَا وَسَقَ ( 17 )
And the Night and all that it enshrouds.
وَالْقَمَرِ إِذَا اتَّسَقَ ( 18 )
And the Moon as it steadily grows to her fullness.
لَتَرْكَبُنَّ طَبَقًا عَن طَبَقٍ ( 19 )
That you will traverse higher and higher from one plane to another. (Civilizations will keep advancing in sciences, and individuals will always have a chance to grow in goodness. Furthermore, evolution of the 'Self' will carry on in the life to come).
فَمَا لَهُمْ لَا يُؤْمِنُونَ ( 20 )
What, then, is the matter with them that they believe not (in a higher form of life?)
