٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَعَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ جَمِيلِ بْنِ صَالِحٍ عَنْ أَبِي عُبَيْدَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ كَانَتْ لَهُ أُمُّ وَلَدٍ وَلَهُ مِنْهَا غُلامٌ فَلَمَّا حَضَرَتْهُ الْوَفَاةُ أَوْصَى لَهَا بِأَلْفَيْ دِرْهَمٍ أَوْ بِأَكْثَرَ لِلْوَرَثَةِ أَنْ يَسْتَرِقُّوهَا قَالَ فَقَالَ لا بَلْ تُعْتَقُ مِنْ ثُلُثِ الْمَيِّتِ وَتُعْطَى مَا أَوْصَى لَهَا بِهِ. وَفِي كِتَابِ الْعَبَّاسِ تُعْتَقُ مِنْ نَصِيبِ ابْنِهَا وَتُعْطَى مِنْ ثُلُثِهِ مَا أَوْصَى لَهَا بِهِ. 
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad and Ali ibn Ibrahim has narrated from his father from all from ibn Mahbub from Jamil ibn Salih from abu ‘ Ubaydah who has narrated the following: “I once asked abu ’Abd Allah , about the case of a man who had a mother of a child from whom he had a boy; and at the time of his death, willed for her two thousand or more; if the heirs can keep her as a slave-girl. He (the Imam) said, ‘No, they cannot keep her as a slave. She becomes free in one-third of the legacy of the deceased and receives what is willed for her.’ “In the book of al- ‘Abbas it is said that she is freed from the share of her son and what is willed for her is given from the one-third of his legacy.”
