It is narrated from Hazrat Abu Salamah bin Abdur Rahman that some people from Jar (Jar is a place on the seashore near Madinah Munawwarah) came to Marwan and asked, "What is the ruling regarding an animal that the sea throws out?" Marwan said: "Its consumption is permissible, and you should go to Sayyiduna Zaid bin Thabit and Sayyiduna Abu Hurairah (may Allah be pleased with them both) and ask them, then come back and inform me what they say." They asked both of them, and both said: "It is permissible." Those people then came back and told Marwan, and Marwan said: "I had already told you so."

Imam Malik (may Allah have mercy on him) said: If a polytheist hunts fish, their consumption is permissible, because the Messenger of Allah (peace and blessings be upon him) said: "The water of the sea is pure, and its dead (animals) are lawful." When the dead of the sea is lawful, then if anyone hunts it, its consumption is permissible.
