Washing of the Deceased
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 24
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «مَا مِنْ عَبْدٍ مُؤْمِنٍ يَغْسِلُ مَيِّتاً مُؤْمِناً وَ يَقُولُ وَ هُوَ يَغْسِلُهُ رَبِّ عَفْوَكَ عَفْوَكَ إِلاَّ عَفَا اَللَّهُ عَنْهُ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "There is no believing servant who washes a deceased believer and says while washing them: Rabbi ‘afwuka ‘afwuka 'O’ Lord عز وجل, Your forgiveness, Your forgiveness,' except that Allah سبحانه وتعالى forgives them."
