The Funeral Prayer (Salat Al-Janazah)
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «مَنْ تَبِعَ جَنَازَةَ اِمْرِئٍ مُسْلِمٍ أُعْطِيَ يَوْمَ اَلْقِيَامَةِ أَرْبَعَ شَفَاعَاتٍ وَ لَمْ يَقُلْ شَيْئاً إِلاَّ قَالَ لَهُ اَلْمَلَكُ وَ لَكَ مِثْلُ ذَلِكَ.
Imam عليه السلام said: "Whoever follows the funeral procession of a Muslim will be granted four intercessions on the Day of Judgment. Whatever supplication or statement they make, the angel will say to them, 'And for you is the same.'"
