مچھلی اور دمِ مسفوح
Please refer to the videos shared in the following thread, this question has been addressed: Discussion 25826
As per my understanding, دَمًا مَسْفُوحًا in its Arabic usage doesn’t apply to this kind of blood coming out of fish that we eat usually. The same way Maytah doesn’t apply to fish in Arabic Usage while in its reality (Haqeeqat) it does apply to fish. Language is extracted from its usage and application and not from its haqeeqat (literal sense). Ghamid Sahab has discussed this linguistic principle at length in the recent response to 23 Questions video ( starting from 42 minutes onward ). You may find this very insightful. Discussion 35124 • Reply 36832 Hopefully, we will also get a response from either Ghamidi Sahab or Hassan Sahab to this Question.
If I go out to eat or buy fish from store, I am not going to ask if it is zabiha or not and will eat the fish beliveing it is halal. I am not going for fishing myself to get zabiha fish. If Allah made it halal then we should not act like bani Israel for doubting in Halal.
