Chapter on Touching the Deceased
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 25
وَقَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ: «إِذَا مَاتَ اَلْمَيِّتُ فِي اَلْبَحْرِ غُسِّلَ وَ حُنِّطَ وَ كُفِّنَ ثُمَّ يُوثَقُ فِي رِجْلِهِ حَجَرٌ وَ يُرْمَى بِهِ فِي اَلْمَاءِ.
The Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام said: "When a person dies at sea, they are washed, anointed (with Hunut), and shrouded. Then a stone should be tied to their leg, and they should be cast into the water."
