Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 51
وَ رَوَى اَلسَّكُونِيُّ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَلَيْهِ اَلسَّلاَمُ: فِي رَجُلٍ أَعْتَقَ أَمَةً وَ هِيَ حُبْلَى فَاسْتَثْنَى مَا فِي بَطْنِهَا قَالَ "اَلْأَمَةُ حُرَّةٌ وَ مَا فِي بَطْنِهَا حُرٌّ لِأَنَّ مَا فِي بَطْنِهَا مِنْهَا".
It is narrated by Al-Sakooni, from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام from his father, Imam Muhammad ibn Ali Al-Baqir عليه السلام, peace be upon him, regarding a man who freed a pregnant bondwoman but excluded what was in her womb. Imam عليه السلام said: "The bondwoman is free, and what is in her womb is also free because what is in her womb is a part of her."
