The Funeral Prayer (Salat Al-Janazah)
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «مَنْ شَيَّعَ جَنَازَةَ مُؤْمِنٍ حَتَّى يُدْفَنَ فِي قَبْرِهِ وَكَّلَ اَللَّهُ بِهِ سَبْعِينَ مَلَكاً مِنَ اَلْمُشَيِّعِينَ يُشَيِّعُونَهُ وَ يَسْتَغْفِرُونَ لَهُ إِذَا خَرَجَ مِنْ قَبْرِهِ إِلَى اَلْمَوْقِفِ.
Imam عليه السلام said: "Whoever accompanies the funeral of a believer until they are buried in their grave, Allah سبحانه وتعالى will assign seventy angels to accompany and seek forgiveness for that person when they rise from their grave to stand at the gathering (on the Day of Judgment)."
