Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 79
وَ رَوَى مَنْصُورُ بْنُ حَازِمٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «مَرِضَ أَبِي عَلَيْهِ اَلسَّلاَمُ يَوْمَ اَلْأَضْحَى فَصَلَّى فِي بَيْتِهِ رَكْعَتَيْنِ ثُمَّ ضَحَّى.
Mansur ibn Hazim narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام who said: "My father عليه السلام fell ill on the day of Eid al-Adha, so he prayed two units (rak'ahs) in his home and then offered the sacrifice."
