6- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ قُلْتُ لأبِي الْحَسَنِ يَهُودِيٌّ أَوْ نَصْرَانِيٌّ كَانَتْ لَهُ عِنْدِي أَرْبَعَةُ آلافِ دِرْهَمٍ فَهَلَكَ أَيَجُوزُ لِي أَنْ أُصَالِحَ وَرَثَتَهُ وَلا أُعْلِمَهُمْ كَمْ كَانَ فَقَالَ لا حَتَّى تُخْبِرَهُمْ.
6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Ali ibn abu Hamzah who has said the following: “I once asked abu al-Hassan . ‘There are four thousand dirhams of a Jew or a Christian and he has died. Is it permissible to reach a settlement about it with his heirs without informing them of the amount?’ He (the Imam) said, ‘No, until you inform them of the amount.’”
