(9) باب حَلاَوَةِ الإِيمَانِ
Narrated Anas:
The Prophet (ﷺ) said, "Whoever possesses the following three qualities will have the sweetness (delight) of faith:1. The one to whom Allah and His Apostle becomes dearer than anything else.2. Who loves a person and he loves him only for Allah's sake.3. Who hates to revert to Atheism (disbelief) as he hates to be throwninto the fire."
