Hadith 565
Sayyiduna Imran bin Husayn (may Allah be pleased with him) reports: The Noble Prophet (peace and blessings be upon him) said: “Whoever fights in the sea in the way of Allah—and Allah knows best who is fighting in His way—then he has fulfilled all his obedience to Allah Almighty, and has completely asked for Paradise from Him, and has entirely fled from Hell.”
