(2) باب طَعْمِ الإِيمَانِ
It was narrated that Anas bin Malik said:
"The messenger of Allah [SAW] said: 'There are three things, whoever attains them will find therein the sweetness of faith: When Allah [SWT], the Mighty and Sublime, and His Messenger [SAW] are dearer to him than all else; when he loves for the sake of Allah [SWT] and hates for the sake of Allah [SWT]; and when a huge fire be lit and he fall into it, than associate anything with Allah [SWT].'"
