Hadith 245

(The book) ‘Fiqh Al-Reza-asws’ – He-asws said: ‘It would be eaten from the fish what had scales for it, and purification of the fish and the locust is their being seized, and do not eat what dies in the water, from the fish and the locust and others, and whenever you hunt (catch) a fish and there is another one in its inside, it can be eaten when there were scales for it’. And it is reported: ‘Do not eat what is in its inside, because it is food, and neither eat the eel, nor the seahorse, nor the Hemibagrus, nor the floater, and it is which dies in the water, so it float on the surface of the water’’. [116]
Note: Detail and clarification of his-asws words: ‘Whenever you hunt (catch) a fish’ – I (Majlisi) am saying, ‘Regarding this subject, two reports have been referred. One of these is what is reported by the Sheykh, by his chain from Al Sakuny, from Abu Abdullah-asws: ‘Ali-asws was asked about a fish whose belly was split, so another fish was found to be in inside it. He-asws said: ‘(You can) eat them all’’. And another is what is reported by an unbroken chain, it can be counted being among the trusted ones, from Abu Abdullah-asws, he (the narrator) said, ‘I said, ‘A man catches a fish and in its inside is (another) fish’. He-asws said: ‘They can both be eaten together’’. Like what is reported by the Sheykh by a chain in which are unknown (narrators), from Ayoub Bin Ayn, ‘From Abu Abdullah-asws, he (the narrator) said, ‘I said to him-asws, ‘May I be sacrificed for you‑asws! What are you-asws saying regarding a snake having swallowed a fish, then it drops (regurgitates it) and it is still alive, being restless, can I eat it? ’ He-asws said: ‘If its scales have stripped off, then do not eat it, and if they have not been stripped off, eat it’’.
