“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
