Volume 8, Book 73, Number 67:
Narrated Anas bin Malik:
The Prophet said, “None will have the sweetness (delight) of Faith (a) till he loves a person and
loves him only for Allah’s sake, (b) and till it becomes dearer to him to be thrown in the fire than to
revert to disbelief (Heathenism) after Allah has brought him out of it, (c) and till Allah and His
Apostle become dearer to him than anything else.”
