Ibn Hazm (رحمه الله) About Agreement Of The Companions (رضي الله عنهم أجمعين)

Allama ibn Hazm (رحمه الله) in his short treatise “an-Nubaz al-kafiya fi akhamil usul ad-deen” said:

“Contrary to this, the one who goes against agreement of the Companions (رضي الله عنهم أجمعين), and deliberately transgresses it, if there is a proof (for him established) and he was informed and (he) still persists – then he would be considered a disbeliever.”

And he also said:

"Each person who comes after and he acts in accordance to agreement of the Companions (رضي الله عنهم أجمعين) and doesn’t contradict it, is considered a believer. The one who goes against agreement because of lack of knowledge regarding such – his words are not taken into account. The one who acts contrary to it, while he knows, and persist in this – is a disbeliever."
