Chapter on Sacrificial Offerings
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 136
وَ رَوَى أَبَانٌ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: «اَلْكَبْشُ يُجْزِي عَنِ اَلرَّجُلِ وَ عَنْ أَهْلِ بَيْتِهِ يُضَحِّي بِهِ ».
It is narrated by Aban from Zurara from Abu Ja'far عليه السلام, who said: "A ram suffices for a man and his household; he may offer it as a sacrifice on their behalf."
