Chapter on Sacrificial Offerings
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 136
وَ كَانَ عَلِيُّ بْنُ اَلْحُسَيْنِ وَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ يَتَصَدَّقَانِ بِثُلُثٍ عَلَى جِيرَانِهِمْ وَ بِثُلُثٍ عَلَى اَلسُّؤَّالِ وَ بِثُلُثٍ يُمْسِكَانِهِ لِأَهْلِ اَلْبَيْتِ.
It is narrated that Imam Ali ibn al-Husayn عليه السلام and Imam Abu Ja'far (Al-Baqir) عليه السلام used to distribute their sacrificial meat in three parts: One-third was given to their neighbors. One-third was given to the needy and beggars. One-third was kept for the members of their household.
