I am not a muhaddith or a naqqad in either to evaluate the status of the Sahih of Imam al-bukhari, yes, however, Imam al-Nawawi, Hafz ibn Hajar al-`Asqalani Hafiz Jalal al-Din al-Suyuti, Imam ibn al-Salah in his muqaddima, Imam Imam al-Sakhawi, and all these great `giants` of the field of Hadith have stated that after the Book of Allah, the most authentic book is the Sahih of Imam al-Bukhari. Though, there is some disagreement with regards which of the two: Sahih Muslim or Sahih Bukhari is more authentic. Some have stated the former, but the majority of Hadith specialists have affirmed through dala`il that it is Imam al-Bukhari`s sahih. Yes, However, never does this mean that there is no authentic hadith that exists besides those that are mentioned in these two, as imam al-bukhari himself has explicitly mentioned that he has not mentioned all of his memorised ahadith in his Empodium of the authentic ahadith narrated with an unbrken chain of transmission through just, upright, established reporters. and Allah knows best Mowlana Muhammed Kalim Azhari
