Abdullah bin Mughira Kanani, may Allah have mercy on him, says that some individuals from Banu Mudlij informed him that they used to go out to sea on planks for hunting, and they would take water with them for drinking, but the time for prayer would also occur while they were at sea. They presented this situation before the Noble Prophet, peace and blessings be upon him, and said: "If we perform ablution with the water we have brought with us, we become thirsty, and if we perform ablution with the sea water, there remains some doubt in our hearts." The Prophet, peace and blessings be upon him, said to them: "The water of the sea is purifying and its dead (animals) are lawful."
