Al-Kāfi - The Book of Wills

Chapter: The Witness for the Will 2- عَلِيُّ بْنُ إِبْرَاهِي٠َ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُ٠َّادٍ عَنِ الْحَلَبِيِّ وَ٠ٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلا٠) قَالَ سَأَلْتُهُ هَلْ تَجُوزُ شَهَادَةُ أَهْلِ ٠ِنْ غَيْرِ أَهْلِ ٠ْ جَازَتْ شَهَادَةُ غَيْرِهِ٠ْ إِنَّهُ لا يَصْلُحُ ذَهَابُ حَقِّ أَحَدٍ.

He (the Imam) said, ‘Yes, it is permissible when witness from the people of his own religion is no available; destroying anyone’s right is not suitable.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (3/8))
