The names of the collections come from the fact that the collections were seen to refer to the roughly 10% of Hadiths that were accurate or sahih (صحيح) in Arabic. The second name refers to the scholar who compiled the list, al-Bukhari (البخاري) or al-Muslim (المسلم). The two scholars, even though they used the same method to determine which hadiths were sahih and which were not, came up with distinct lists of what hadiths they believed were sahih. While they agreed on a large number of hadiths, the disagreements are noticeable and this is why there are different hadiths in the different collection. Other hadith collectors, like Abu Darda have still other hadiths that they consider sahih, but are rejected by both al-Bukhari and al-Muslim.
