Qur'an 9:110 · At-Tawba

لَا يَزَالُ بُنْيَٰنُهُمُ ٱلَّذِى بَنَوْا۟ رِيبَةًۭ فِى قُلُوبِهِمْ إِلَّآ أَن تَقَطَّعَ قُلُوبُهُمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ

(110) Their building which they built will not cease to be a [cause of] skepticism in their hearts until their hearts are cut [i.e., stopped]. And Allāh is Knowing and Wise.
