Washing of the Deceased
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 24
وَقَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ: «يَغْسِلُ اَلْمَيِّتَ أَوْلَى اَلنَّاسِ بِهِ أَوْ مَنْ يَأْمُرُهُ اَلْوَلِيُّ بِذَلِكَ.
The Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام said: "The one who washes the deceased should be the closest person to them or the one whom the guardian (Wali) of the deceased appoints for this task."
