Hadith #3

3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ رَفَعَهُ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِذَا مَاتَ الرَّجُلُ فِي السَّفِينَةِ وَلَمْ يُقْدَرْ عَلَى الشَّطِّ قَالَ يُكَفَّنُ وَيُحَنَّطُ وَيُلَفُّ فِي ثَوْبٍ وَيُلْقَى فِي الْمَاءِ.

3. A number of our people have narrated from Sahl ibn Ziyad in a marfu‘ manner has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘If one dies in a ship and it is not possible to bring him to the shore, shroud and hunut are done for him, after wrapping in a piece of cloth, is thrown into the water.’”
