question #3 Sahih al-Bukhari 6574, Book 81, Hadith 162 : How do different companions of the Prophet (ﷺ) contribute to the understanding of hadiths?

Abu Sa`id was sitting in the company of Abu
Huraira and he did not deny anything of his narration till he reached his saying: “All this and as much
again therewith are for you.” Then Abu Sa`id said, “I heard Allah’s Messenger (ﷺ) saying, ‘This is for you
and ten times as much.’ ” Abu Huraira said, “In my memory it is ‘as much again therewith.’ ”
