عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ مُحَمَّدِ بْنِ قَيْسٍ عَنْ أَبِي جَعْفَرٍ ( عليه السلام )
قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) لَا تَسْتَرْضِعُوا الْحَمْقَاءَ فَإِنَّ اللَّبَنَ يُعْدِي وَ إِنَّ الْغُلَامَ يَنْزِعُ إِلَى اللَّبَنِ يَعْنِي إِلَى الظِّئْرِ فِي الرُّعُونَةِ وَ الْحُمْقِ .
8. Ali ibn Ibrahim has narrated from his father from ibn abu Najran from ‘Asem ibn Hamid from Muhammad ibn Qays who has said the following:
“This is a narration of abu Ja‘far 
, from the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause. He (the Messenger of Allah) has said, ‘You must not hire a dimwitted woman for breastfeeding; the milk spreads and the boy is drawn to the milk, that is, to the frivolity and dimwittedness of the breastfeeding woman.’”
