Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 36
وَ كَتَبَ أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى إِلَى عَلِيِّ بْنِ مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ: اِمْرَأَةٌ أَرْضَعَتْ عَنَاقاً مِنَ اَلْغَنَمِ بِلَبَنِهَا حَتَّى فَطَمَتْهَا فَكَتَبَ عَلَيْهِ اَلسَّلاَمُ "فِعْلٌ مَكْرُوهٌ وَ لاَ بَأْسَ بِهِ".
Ahmad ibn Muhammad ibn Isa wrote to Imam Ali ibn Muhammad Al-Hadi عليه السلام, inquiring about a woman who nursed a young goat with her milk until it was weaned. Imam عليه السلام wrote in reply: "It is a disliked (makruh) act, but there is no harm in it."
