I suppose this to be done freely by reporters of al-Bukhari’s book, since he – as previously referred to – has left the book in a draft-like form, so in the names cited by him here neither preferability nor priority nor old age, the aspects of priority in ranking are considered. When none of these considerations being observed by him, it indicated that he had written each biography separately, the fact resulting in the narrators annexing some of them to each other at random.

Al-Bukhari was the first to discern between the sahih tradition – in his view – and non-sahih one, so he selected for his book those traditions which he thought to be sahih (correct).

Because tadwin (writing down) before his era was done – as stated earlier – through gathering the correct and incorrect traditions without any discernment, as this can be clearly seen in Musnad Ahmad and other Musnads, or by adding some things to the Messenger’s traditions and the ’ utterances and Followers’ verdicts, as this can be found in Malik’s Muwatta’. For all this, al-Bukhari’s book (Sahih) was thought to be the first book compiled that containing sahih traditions.

The traditionsts criticized him in a hundred and ten traditions, of which the reporting of thirty-two ones was concurringly agreed by Muslim, and seventy-eight ones were reported by him alone. 568 Those for whom al-Bukhari not Muslim has reported alone were four hundred thirty plus men, among whom eighty ones 569 charged him with weakness. Whereas the number of traditionists for whom Muslim alone reported amounted to 620 men, among whom 160 ones were telling of presence of weakness.

And the number of traditions for which they were both criticized amounted to two hundred and ten ones, of which eighty ones were independently related by al-Bukhari, with the rest being related by Muslim. 570 About the traditions criticized by al-Daraqutni, Ibn Hajar is reported to have said: There is controversy regarding the veracity of these traditions, and they were not approved or accepted as in the case of the most of the book.
