10. Abu Ali al-Ash‘ariy has narrated from al-Hassan ibn Ali from his uncle Muhammad ibn Sulayman ibn Ja‘far who has said the following: “Ishaq, fisherman, narrated to me the following, ‘Once we went out with fish to meet abu al-Hassan, al-Rida’ . We went out of al-Madinah and he (the Imam) was coming from his journey and he (the Imam) said, ‘Fie upon, you O so and so, perhaps you have fish with you.’ I replied, ‘Yes, O my master, I pray to Allah to keep my soul in service for your cause.’ He (the Imam) said, ‘Bring them down.’ He (the Imam) then said, ‘Perhaps it is Zahw.’ I replied, ‘Yes, it is and I showed him (the Imam) Zahw ’ He (the Imam) said, ‘Ride your stumpers; we cannot use them for food.’ Al- Zahw is a fish that has no scales.’”
