The slave is not afflicted with a punishment greater than the hardening of the heart and being distant from Allah. For the Fire was created to melt the hardened heart. The most distant heart from Allah is the heart which is hardened. If the heart becomes hardened, the eye becomes dry. - ابن قيم الجوزية
I can but pray the Father o' a' to haud his e'e upon her, an' his airms aboot her, an' keep aff the hardenin' o' the hert 'at despises coonsel! - George MacDonald
