مُحَمَّدُ بْنُ يَحْيَى عَنْ سَلَمَةَ بْنِ الْخَطَّابِ عَنْ مُحَمَّدِ بْنِ مُوسَى عَنْ مُحَمَّدِ بْنِ الْعَبَّاسِ بْنِ الْوَلِيدِ عَنْ أَبِيهِ عَنْ أُمِّهِ أُمِّ إِسْحَاقَ بِنْتِ سُلَيْمَانَ قَالَتْ نَظَرَ إِلَيَّ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) وَ أَنَا أُرْضِعُ أَحَدَ بَنِيَّ مُحَمَّداً أَوْ إِسْحَاقَ فَقَالَ يَا أُمَّ إِسْحَاقَ لَا تُرْضِعِيهِ مِنْ ثَدْيٍ وَاحِدٍ وَ أَرْضِعِيهِ مِنْ كِلَيْهِمَا يَكُونُ أَحَدُهُمَا طَعَاماً وَ الْآخَرُ شَرَاباً .
2. Muhammad ibn Yahya has narrated from Salmah ibn al-Khattab from Muhammad ibn Musa from Muhammad ibn al-‘ Abbas ibn al- Walid from his father from ‘Umm Ishaq daughter of Sulayman who has said the following: “Abu ‘Abd Allah , once looked to me when I was breastfeeding one of my sons, Muhammad or Ishaq and he (the Imam) said, ‘O ‘Umm Ishaq, do not breastfeed him from one breast only. Breastfeed him from both breasts; one is food and the other is the drink for him.’”
