The Funeral Prayer (Salat Al-Janazah)
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «أَوَّلُ مَا يُتْحَفُ بِهِ اَلْمُؤْمِنُ فِي قَبْرِهِ أَنْ يُغْفَرَ لِمَنْ تَبِعَ جَنَازَتَهُ.
Imam عليه السلام said: "The first gift given to a believer in their grave is the forgiveness granted to those who followed their funeral procession."
