مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْعَبَّاسِ بْنِ مَعْرُوفٍ عَنْ حَمَّادِ بْنِ عِيسَى عَنِ الْهَيْثَمِ عَنْ مُحَمَّدِ بْنِ مَرْوَانَ قَالَ
قَالَ لِي أَبُو جَعْفَرٍ ( عليه السلام ) اسْتَرْضِعْ لِوَلَدِكَ بِلَبَنِ الْحِسَانِ وَ إِيَّاكَ وَ الْقِبَاحَ فَإِنَّ اللَّبَنَ قَدْ يُعْدِي .
12. Muḥammad ibn Yaḥyā narrated from Aḥmad ibn Muḥammad, from al-‘Abbās ibn Ma‘rūf, from Ḥammād ibn ‘Īsā, from al-Haytham, from Muḥammad ibn Marwān, who said that Abū Ja‘far 
said to me:
'Seek a wet nurse for your child from among the beautiful women, and avoid the ugly ones, for the milk can have an influence.'
