٤- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ إِسْمَاعِيلَ بْنِ مَرَّارٍ عَنْ يُونُسَ عَنْ عُمَرَ بْنِ أَبِي حَفْصٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) يَقُولُ اتَّقُوا اللهَ وَعَلَيْكُمْ بِأَدَاءِ الأمَانَةِ إِلَى مَنِ ائْتَمَنَكُمْ وَلَوْ أَنَّ قَاتِلَ عَلِيِّ بْنِ أَبِي طَالِبٍ (عَلَيْهِ السَّلام) ائْتَمَنَنِي عَلَى أَمَانَةٍ لأدَّيْتُهَا إِلَيْهِ.
4. Ali ibn Ibrahim has narrated from his father from ‘Isma’il ibn Marrar from Yunus from ‘Umar ibn abu Hafs who has said the following: “I heard abu ‘Abd Allah , saying, ‘You must maintain piety before Allah and you must return a trust to the one who has entrusted you with it. Even if the assassin of Ali ibn abu Talib entrusted me with something, I had to return it to him safely.’”
