٤- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ دُرُسْتَ بْنِ أَبِي مَنْصُورٍ عَنْ أَبِي الْمَغْرَاءِ عَنْ رَجُلٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ إِنَّ اللهَ عَزَّ وَجَلَّ أَدْخَلَ الأبَوَيْنِ عَلَى جَمِيعِ أَهْلِ الْفَرَائِضِ فَلَمْ يَنْقُصْهُمَا مِنَ السُّدُسِ لِكُلِّ وَاحِدٍ مِنْهُمَا وَأَدْخَلَ الزَّوْجَ وَالزَّوْجَةَ عَلَى جَمِيعِ أَهْلِ الْمَوَارِيثِ فَلَمْ يَنْقُصْهُمَا مِنَ الرُّبُعِ وَالثُّمُنِ. 
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Durust ibn abu Mansur from abu al-Mighra’ from a man who has narrated the following: “Abu Ja‘far , has said, ‘Allah, most Majestic, most Glorious, has placed parents with all other heirs who have ordained shares and nothing is reduced from their one-sixth for each parent and He has placed a husband and wife with all other heirs but nothing is reduced from one-fourth and one-eighth.’”
