From Ibn Al-Qassar [D. 378 A.H.] [رحمه الله] who said:

❝The Companions are the ones who conveyed the Sunnan [the practice of the Prophet] and they explained it, therefore, it is obligatory to follow their path.❞

[Sharh Saheeh Al-Bukhari By Ibn Battal, (4/369) | Translated By Abbas Abu Yahya Miraath al-Anbiyya]
