What is the matter with them that they believe not?

فَلَا أُقْسِمُ بِالشَّفَقِ  

وَاللَّيْلِ وَمَا وَسَقَ  

وَالْقَمَرِ إِذَا اتَّسَقَ  

لَتَرْكَبُنَّ طَبَقًا عَن طَبَقٍ  

فَمَا لَهُمْ لَا يُؤْمِنُونَ  

وَإِذَا قُرِئَ عَلَيْهِمُ الْقُرْآنُ لَا يَسْجُدُونَ ۩  

بَلِ الَّذِينَ كَفَرُوا يُكَذِّبُونَ  

وَاللَّهُ أَعْلَمُ بِمَا يُوعُونَ  

فَبَشِّرْهُم بِعَذَابٍ أَلِيمٍ  

إِلَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ

So I swear by the afterglow of sunset;

And by the night and whatever it gathers in its darkness;

And by the moon when it is at the full,

You shall certainly travel from stage to stage (in this life and in the Hereafter).

What is the matter with them, that they believe not?

And when the Qur'an is recited to them, they fall not prostrate,

Nay, (on the contrary), those who disbelieve, belie (Prophet Muhammad (sallAllaahu 'alayhi wa sallam) and whatever he brought, i.e. this Qur'an and Islamic Monotheism, etc.).

And Allah knows best what they gather (of good and bad deeds),

So announce to them a painful torment.

Save those who believe and do righteous good deeds, for them is a reward that will never come to an end (i.e. Paradise).

Surah al-Inshiqaq [84:16-25]
