If i know Arabic, should i purchase the original collection of Sahih Al Bukhari or should I purchase Fath Al Bari? Which would be more beneficial? جزاك اللهُ خيرًا

Ustadh AbdulAziz al-Haqqan

Fath albari is not an easy read, so if u need it as u r going to study it under a sheikh then fine, if not then postpone it for its proper time.
