9- عَنْهُ عَنْ وُهَيْبِ بْنِ حَفْصٍ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ لاعَنَ امْرَأَتَهُ قَالَ يَلْحَقُ الْوَلَدُ بِأُمِّهِ وَيَرِثُهُ أَخْوَالُهُ وَلا يَرِثُهُمْ فَسَأَلْتُهُ عَنِ الرَّجُلِ إِنْ أَكْذَبَ نَفْسَهُ قَالَ يَلْحَقُ بِهِ الْوَلَدُ.

9. It is narrated from the narrator of the previous Hadith and Wuhayb ibn Hafs from abu Basir who has narrated the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who forms Mula ‘anah against his wife. He (the Imam) said, ‘The child is joined with his mother and his maternal uncle inherits his legacy but he cannot inherit them. I then asked, ‘What happens if he calls himself a liar?’ He (the Imam) said, ‘The child is joined with him.’”
