Terrors of the Day of Judgement

Allah says that the torment will befall the disbelievers.

يَوْمَ تَكُونُ السَّمَآءُ كَالْمُهْلِ

تَدْعُو مَنْ أَدْبَرَ‌ وَتَوَلَّىٰ وَجَمَعَ فَأَوْعَىٰ (It will call him who had turned his back and fled away (from the truth.) and accumulated (wealth) and hoarded (it)....70:17, 18). The phrase 'accumulated wealth' signifies 'wealth accumulated by unlawful means' and the phrase 'hoarded it' signifies 'not fulfilling the pecuniary obligations as imposed by the Shari` ah', as is confirmed by authentic ahadi'th.
