9:110
لَا يَزَالُ بُنْيَـٰنُهُمُ ٱلَّذِى بَنَوْا۟ رِيبَةً فِى قُلُوبِهِمْ إِلَّآ أَن تَقَطَّعَ قُلُوبُهُمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ
lā yazālu bun'yānuhumu alladhī banaw rībatan fī qulūbihim illā an taqaṭṭaʿa qulūbuhum wal-lahu ʿalīmun ḥakīmun
the building they have founded will always be a source of doubt within their hearts, until their hearts are cut to pieces. God is all knowing and wise.
The building which they built will never cease to be a cause of hypocrisy and doubt in their hearts unless their hearts are cut to pieces. (i.e. till they die). And Allâh is All-Knowing, All-Wise.
