Sayyiduna Abu al-Tufayl (may Allah be pleased with him) said that Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) was asked about the dead of the sea, and he said: Its water is pure and its dead are lawful. (b) Amr bin Dinar and Abu al-Zubayr heard a Companion (may Allah be pleased with him) say: Everything in the sea is slaughtered.
