Qur'an 9:110

لَا يَزَالُ بُنْيَـٰنُهُمُ ٱلَّذِى بَنَوْا۟ رِيبَةً فِى قُلُوبِهِمْ إِلَّآ أَن تَقَطَّعَ قُلُوبُهُمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ

“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.”
