Question
Is the blood of fish impure (najis) in Islamic law?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
Answer
Allah has stated in the Qur’an;
“Lawful to you is the pursuit of water game and its use for food for the benefit of yourselves and those who travel” (Surah Maaidah v.96)
Furthermore, Saaiduan Ibn Umar relates that Allah’s Messenger (PBUH) said: “Made lawful for you are the flesh of two dead animals and two types of blood. As for the two dead animals, they are the locust and the fish. And as for the two types of blood, they are the blood of the spleen and the liver.”
(Musnad Ahmad, Sunan Ibn Majah & Sunan al-Daraqutni)
Regarding your question from the above-mentioned sources, we can understand that the apparent blood of a fish is not impure.
Only Allah knows best.
