Fish with Scales...
Ali Bin Ibrahim, from his father, from Abdullah Bin Al Mugheira, from Abdullah Bin Sinan, from; Abu Abdullah -asws narrates that Amir Al-Momineen Ali -asws Bin Abu Talib -asws was at Al-Kufa, riding a mule of Rasool-Allah -saww . Then he -asws passed by a fish market, so he -asws was saying: ‘Neither eat, nor pursue the fish which do not have scales on it ’.
A number of our companions, from Sahl Bin Ziyad, and Muhammad Bin Yahya, from Ahmad Bin Muhammad, altogether from Ibn Mahboub, and Ahmad Bin Muhammad Bin Abu Nasr, altogether from Al A’ala, from Muhammad Bin Muslim who said, ‘Abu Ja’far -asws made me read something from the Book of Ali -asws , so there was in it – you have been forbidden from the catfish, and the glyptothorax (mountain catfish), and the sea horse, and the floating fish (dead), and the spleen.
I said, ‘O son -asws of Rasool-Allah -saww ! They come to us with fish with no scales on it’. So he -asws said: ‘Eat from the fish what has scales for it, and what does not have scales for it, so do not eat it’. [4] Additional Ahadith on fish with scale are included in Appendix.
