According to the Hanafi Madhhab, oyster sauce is generally considered to be avoided because it contains extracts of oyster.
Here's a breakdown of why:
- Oyster Extract: The primary concern revolves around the presence of oyster extract.
- Hanafi Madhhab Ruling: The Hanafi school of thought tends to avoid foods containing extracts from seafood considered impermissible.
