5- أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ حَدَّثَنِي أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) أَنَّ أَبَاهُ كَانَتْ عِنْدَهُ امْرَأَةٌ مِنَ الْخَوَارِجِ أَظُنُّهُ قَالَ مِنْ بَنِي حَنِيفَةَ فَقَالَ لَهُ مَوْلًى لَهُ يَا ابْنَ رَسُولِ اللهِ إِنَّ عِنْدَكَ امْرَأَةً تَبَرَّأُ مِنْ جَدِّكَ فَقُضِيَ لأبِي أَنَّهُ طَلَّقَهَا فَادَّعَتْ عَلَيْهِ صَدَاقَهَا فَجَاءَتْ بِهِ إِلَى أَمِيرِ الْمَدِينَةِ تَسْتَعْدِيهِ فَقَالَ لَهُ أَمِيرُ الْمَدِينَةِ يَا عَلِيُّ إِمَّا أَنْ تَحْلِفَ وَإِمَّا أَنْ تُعْطِيَهَا [حَقَّهَا] فَقَالَ لِي قُمْ يَا بُنَيَّ فَأَعْطِهَا أَرْبَعَمِائَةِ دِينَارٍ فَقُلْتُ لَهُ يَا أَبَهْ جُعِلْتُ فِدَاكَ أَلَسْتَ مُحِقّاً قَالَ بَلَى يَا بُنَيَّ وَلَكِنِّي أَجْلَلْتُ اللهَ أَنْ أَحْلِفَ بِهِ يَمِينَ صَبْرٍ.

5. Ahmad ibn Muhammad has narrated from Ali ibn al-Hakam from Ali ibn abu Hamzah from abu Basir who has narrated the following: “Abu Ja‘far, ‘Alayhi al-Salam, once spoke to me about his father, ‘Alayhi al-Salam. He (the Imam) was with a woman of al-Khawarij, I (the narrator) think he said, ‘banu Hanifah.’ His mawla (friend or servant) said to him (the Imam), ‘O child of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, you have a woman who denounces your grandfather.’ (Abu Ja’far, ‘Alayhi al-Salam, said) ‘My father divorced her. She presented a claim for her mahr (dower) against him (the Imam) and brought him (the Imam) before the Amir (governor) of al-Madinah who asked him (the Imam), “O Ali, you must take an oath or pay her right.” He (the Imam) asked me to go and bring four hundred dinars. I then asked, “Father, I pray to Allah to keep my soul in service for your cause, were you not the rightful party?” He (the Imam) replied, “Yes, son but I because of the Glory of Allah did not want to swear by Allah which is made binding upon me.’””
