“There are three things, whoever has them has found the taste
of
faith (One of the narrators) Bundar said: ‘The sweetness of
faith;
When he loves a man and only loves him for the sake of Allah.
When
Allah and His Messenger are more beloved to him than anything
else;
and when being thrown into the fire is dearer to him than going
back
to disbelief after Allah has saved him from it.”
Sunan Ibn Majah Book 36, Hadith 108
