لَا يَزَالُ بُنْيَٰنُهُمُ ٱلَّذِى بَنَوْا۟ رِيبَةً فِى قُلُوبِهِمْ إِلَّآ أَن تَقَطَّعَ قُلُوبُهُمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ
Commentary:
The words, unless their hearts be torn to pieces, are intended to hint that as the hearts of the hypocrites will never be cut into pieces, so the disquietude of their hearts will continue forever. Or, the words signify that the disquietude of their hearts will cease only when they repent so deeply that their hearts are, as it were, torn up with regret and repentance.
