4664 - : وَ نَظَرَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ إِلَى أُمِّ إِسْحَاقَ بِنْتِ سُلَيْمَانَ وَ هِيَ تُرْضِعُ أَحَدَ اِبْنَيْهَا مُحَمَّداً أَوْ إِسْحَاقَ فَقَالَ "يَا أُمَّ إِسْحَاقَ لاَ تُرْضِعِيهِ مِنْ ثَدْيٍ وَاحِدٍ وَ أَرْضِعِيهِ مِنْ كِلَيْهِمَا يَكُونُ أَحَدُهُمَا طَعَاماً وَ اَلْآخَرُ شَرَاباً".
Hadith.4664 - Imam Jafar ibn Muhammad Al-Sadiq 
looked at Umm Ishaq bint Sulayman while she was breastfeeding one of her two sons, either Muhammad or Ishaq, and Imam said:
"O Umm Ishaq, do not nurse him from only one breast; rather, nurse him from both. One will serve as food and the other as drink."
