Hadith 17:

It was narrated from Anas ibn Malik (r.a) that the Prophet (s.a.w) said: «There are three characteristics, whoever attains them has found the sweetness of faith: when Allah and His Messenger are dearer to him than all else, when he loves a man and does not love him except for the sake of Allah, and when he would hate to return to disbelief after Allah has saved him from it as he would hate to be thrown into the Fire.»
