I heard that famous scholars like Imam Bhukhari[rah], Imam Muslim[rah] were born after the period of Imams of Maddhabs(Abuhanifa[rah],Shafi[rah]).
So,they should heard about Fiqh(Maddhab) and they should mention something about that in their books or to their students.
What did they(Imam Bhukhari[rah], Imam Muslim[rah]) say about the Madhhabs?
