The Sufficient (Vol 6) · Hadith 175 (#Ḥadīth #9)

عَلِيٌّ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَ أَمِيرُ الْمُؤْمِنِينَ ( صلوات الله عليه ) يَقُولُ لَا تَسْتَرْضِعُوا الْحَمْقَاءَ فَإِنَّ اللَّبَنَ يَغْلِبُ الطِّبَاعَ وَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) لَا تَسْتَرْضِعُوا الْحَمْقَاءَ فَإِنَّ الْوَلَدَ يَشِبُّ عَلَيْهِ .

9. Ali has narrated from Harun ibn Muslim from Mas’adah who has said the following: “Abu ‘Abd Allah , has said that ’Amir al-Mu’minin would say, ‘Do not hire a dimwitted woman for breastfeeding: milk overpowers natural manners. The Messenger of Allah has said, “Do not hire a dimwitted woman for breastfeeding; with such milk the child grows up.’””
