The Funeral Prayer (Salat Al-Janazah)
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَقَالَ عَلَيْهِ اَلسَّلاَمُ لِإِسْحَاقَ بْنِ عَمَّارٍ إِذَا حَمَلْتَ جَوَانِبَ اَلسَّرِيرِ سَرِيرِ اَلْمَيِّتِ خَرَجْتَ مِنَ اَلذُّنُوبِ كَمَا وَلَدَتْكَ أُمُّكَ.
Imam عليه السلام said to Ishaq ibn Ammar: "When you carry the sides of the bier of the deceased, you will be cleansed of your sins as if you were just born from your mother."
