18- مُحَمَّدُ بْنُ يَحْيَى عَنْ عَبْدِ اللهِ بْنِ جَعْفَرٍ قَالَ كَتَبْتُ إِلَى أَبِي مُحَمَّدٍ امْرَأَةٌ أَرْضَعَتْ وَلَدَ الرَّجُلِ هَلْ يَحِلُّ لِذَلِكَ الرَّجُلِ أَنْ يَتَزَوَّجَ ابْنَةَ هَذِهِ الْمُرْضِعَةِ أَمْ لا فَوَقَّعَ لا لا تَحِلُّ لَهُ.

18. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Ja’far who has said the following: “I once wrote to abu Muhammad, Alayhi al-Salam, and asked, ‘A woman has breastfed the son of a man; if the man can marry the daughter of breastfeeding woman. He (the Imam) signed the answer, ‘No, he cannot marry because it is not lawful for him.’”
