3- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنِ الرَّجُلِ الْمُسْلِمِ هَلْ يَرِثُ الْمُشْرِكَ قَالَ نَعَمْ وَلا يَرِثُ الْمُشْرِكُ الْمُسْلِمَ.

3. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ‘Isa from Yunus from Zur’ah from Sama‘ah who has narrated the following: “I once asked abu ‘Abd Allah, Alayhi al-Salam, if a Muslim can inherit from a pagan. He (the Imam) said, ‘Yes, but a pagan cannot inherit from the Muslim.’”
