Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 25
وَ سَأَلَهُ مَنْصُورُ بْنُ حَازِمٍ: عَنِ اَلرَّجُلِ يُسَافِرُ مَعَ اِمْرَأَتِهِ فَتَمُوتُ أَ يُغَسِّلُهَا قَالَ «نَعَمْ وَ أُمَّهُ وَ أُخْتَهُ وَ نَحْوَهُمَا يُلْقِي عَلَى عَوْرَتِهَا خِرْقَةً وَ يُغَسِّلُهَا.
Mansour ibn Hazim asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام about a man traveling with his wife, and She dies. Should he wash her? Imam عليه السلام replied: "Yes, as well as his mother, sister, and similar relatives. He should cover her private parts with a cloth and then perform the washing."
