١- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ مِهْزَمٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فِي عَبْدٍ مُسْلِمٍ وَلَهُ أُمٌّ نَصْرَانِيَّةٌ وَلِلْعَبْدِ ابْنٌ حُرٌّ قِيلَ أَرَأَيْتَ إِنْ مَاتَتْ أُمُّ الْعَبْدِ وَتَرَكَتْ مَالا قَالَ يَرِثُهُ ابْنُ ابْنِهَا الْحُرُّ. 
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from abu Ayyub from Mehzam who has narrated the following: “About the case of a slave who is a Muslim and has a Christian mother and a free son, it was asked what happens if the mother of the slave dies leaving a certain amount of assets, abu ‘Abd Allah , said, ‘Her free grandson inherits it.’”
