Chapter on Breastfeeding
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 47
وَ رَوَى مُحَمَّدُ بْنُ أَبِي عُمَيْرٍ عَنْ يُونُسَ بْنِ يَعْقُوبَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اِمْرَأَةٍ دَرَّ لَبَنُهَا مِنْ غَيْرِ وِلاَدَةٍ فَأَرْضَعَتْ جَارِيَةً وَ غُلاَماً بِذَلِكَ اَللَّبَنِ هَلْ يَحْرُمُ بِذَلِكَ اَللَّبَنِ مَا يَحْرُمُ مِنَ اَلرَّضَاعِ قَالَ "لاَ".
Muhammad ibn Abi Umayr narrated from Yunus ibn Yaqub from Abu Abdullah عليه السلام who said: I asked Imam عليه السلام about a woman whose milk flowed without childbirth, and she breastfed a girl and a boy with that milk. Does this milk create the same prohibitions as regular breastfeeding? Imam عليه السلام replied: "No."
