What is the meaning of "narrated or reported by Al-Bukhari in Al-Adab Al-Mufrad" and "Al-Bukhari in his Tarikh" and "Al-Bukhari T" and "Al-Bukhari N"? And how is the word "المفرد" (al-mufrad) vocalized in "الأدب المفرد" (Al-Adab Al-Mufrad)?

Al-Bukhari has several works, among them: "Sahih Al-Bukhari," which is specifically for authentic hadiths, and "Al-Adab Al-Mufrad" and "Al-Tarikh," which are not specific to authentic hadiths. So, if it is said: "Narrated by Al-Bukhari" without qualification, it means he narrated it in his Sahih with a complete chain of transmission (musnad). However, if he narrated it as a suspended narration, it is said: "Narrated by Al-Bukhari as a suspended narration (ta'liqan)." And if it is said: "He narrated it in Al-Adab Al-Mufrad" or "in Al-Tarikh," then this must be specified.
