Sayyiduna Jabir (may Allah be pleased with him) used to say: Whatever the sea casts out, or whatever the water recedes from, or whatever is caught in it, eat it; and whatever dies in it and then floats up, do not eat it.
A number of narrators reported it from Abu al-Zubayr from Jabir as his own saying (mawquf); Abu Ahmad al-Zubayri differed from them and narrated it from al-Thawri as a saying of the Prophet (marfu'), and he erred in that.
