Chapter 19 | Testimony of the Members of all other Nations
7- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ ضُرَيْسٍ الْكُنَاسِيِّ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ عَنْ شَهَادَةِ أَهْلِ الْمِلَلِ هَلْ تَجُوزُ عَلَى رَجُلٍ مِنْ غَيْرِ أَهْلِ مِلَّتِهِمْ فَقَالَ لا إِلا أَنْ لا يُوجَدَ فِي تِلْكَ الْحَالِ غَيْرُهُمْ فَإِنْ لَمْ يُوجَدْ غَيْرُهُمْ جَازَتْ شَهَادَتُهُمْ فِي الْوَصِيَّةِ لأنَّهُ لا يَصْلُحُ ذَهَابُ حَقِّ امْرِئٍ مُسْلِمٍ وَلا تَبْطُلُ وَصِيَّتُهُ.
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Mahbub from abu Ayyub ‘Abd al-’Aziz al-‘ from Durays al-Kunasiy who has narrated the following: “I once asked abu Ja‘far , about the testimony of people of other nations if they can be appointed as witness. He (the Imam) said, ‘No, unless no one else can be found, in which case their bearing testimony about a will is permissible, because it is not proper to invalidate the right of a Muslim man and void his will.’”
