Imam Bukhari’s Teachers: Four Legends
Imam Bukhari, rahimahullah, studied from over 1000 teachers. The best of them were also the greatest scholars of his time. This is an important point: in the previous generation, four scholars lived who were stars of hadith sciences. Imam Bukhari not only studied under all four of these masters of hadith sciences, but he became the main student or protege of all four scholars.
As teachers, in that time, each teacher would teach many students.
