Is the authenticity of Sahih al-Bukhari specific to the chain of narrators (sanad) or to the text (matn), and which books are most authentic in their text?

All of the hadiths in Sahih al-Bukhari are authentic in chain of transmission (sanad) and text (matn), and the authenticity of the text is stronger and more evident. The majority of the Ummah has unanimously accepted its contents with approval. Sahih al-Bukhari is the most authentic book after the Qur’an, and the most beneficial, due to its strongest connectedness (ittisal), its most reliable narrators, and its precedence over others in terms of combining conditions of authenticity and jurisprudential benefits, and because it only mentions a hadith if it is firmly established in the soundest ways. As for Sahih Muslim, its distinction lies in its good arrangement of hadiths by gathering their various narrations and wordings in one place. Some may prefer Muslim over Bukhari in terms of care for the wordings of the texts and narrating the hadith in its entirety without dividing it according to the chapters of jurisprudence.
