[Machine] The Messenger of Allah ﷺ said that two things are permissible for us: dead meat and blood. As for the dead meat, it refers to locusts and fish, while the blood refers to spleen and liver. All of these are from the weak animals, which Yahya bin Ma'een had declared as such. However, Ahmad bin Hanbal and Ali bin Al-Madini considered Abdullah bin Zaid as reliable, except that the authentic narration from this hadith is the first one.
