Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 49
وَ رُوِيَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ أَبِي بَصِيرٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يُعْتِقُ اَلرَّجُلَ فِي كَفَّارَةِ يَمِينٍ أَوْ ظِهَارٍ لِمَنْ يَكُونُ اَلْوَلاَءُ قَالَ "لِلَّذِي أَعْتَقَ".
It is narrated from Asim ibn Humayd, from Abu Basir, who said: I asked Abu Abdullah عليه السلام, about a man who frees another man as an expiation for breaking an oath or for zihar (a prohibited declaration regarding one's wife). Imam عليه السلام said: "The wala' (bond of loyalty) belongs to the one who freed him."
