Al-Adab al-Mufrad (Arabic: الأدب المفرد) is a topical book of hadiths collected by Muhammad al-Bukhari addressing the question of perfecting Muslim manners.
[1][2][3] The book has hadith about the manners of Islamic prophet Muhammad.
[4] This book is overshadowed by Imam al-Bukhari's other book, the classic collection of hadiths, al-Jami' al-Sahih.
[5] Although al-Adab al-Mufrad was also a significant work of his, Imam al-Bukhari did not make it a requirement that the hadiths within al-Adab al-Mufrad meet the very strict and stringent conditions of authenticity which he laid down for his al-Jami' al-Sahih.
However, based on the writings of later scholars who explained, commented and/or traced and classified the chains of narration within al-Adab al-Mufrad, most of the narrations within it were ruled to be authentic or at the least sound.
