Did Imam Bukhari write the chapter headings in Adab Mufrad just like he did for his Sahih? Can his opinions be deduced from the chapter headings in Adab Mufrad?
Yes, the chapters in Al-Adabul Mufrad are indeed formulated by the author himself; Imam Bukhari (rahimahullah).
Generally, these chapter headings do represent the views of the authors.
And Allah Ta’ala Knows best,
