عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَ عَلِيِّ بْنِ مُحَمَّدٍ الْقَاسَانِيِّ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ الْجَوْهَرِيِّ عَنْ سُلَيْمَانَ بْنِ دَاوُدَ الْمِنْقَرِيِّ قَالَ سُئِلَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) عَنِ الرَّضَاعِ فَقَالَ لَا تُجْبَرُ الْحُرَّةُ عَلَى رَضَاعِ الْوَلَدِ وَ تُجْبَرُ أُمُّ الْوَلَدِ .

4. Ali ibn Ibrahim has narrated from his father and Ali Muhammad al-Qasaniy from al-Qasim ibn Muhammad al-Jawhariy from Sulayman ibn Dawud al-Minqariy who has said the following: “Once abu ‘Abd Allah, ‘Alayhi al-Salam, was asked about breastfeeding. He (the Imam) said, ‘A free woman cannot be forced to breastfeed; but the mother (who is a slave-girl) of child can be made to breastfeed.’”
