مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُوسَى بْنِ بَكْرٍ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ ( عليه السلام ) قَالَ يُشْهِدُ رَجُلَيْنِ إِذَا طَلَّقَ وَ إِذَا رَجَعَ فَإِنْ جَهِلَ فَغَشِيَهَا فَلْيُشْهِدِ الْآنَ عَلَى مَا صَنَعَ وَ هِيَ امْرَأَتُهُ فَإِنْ كَانَ لَمْ يُشْهِدْ حِينَ طَلَّقَ فَلَيْسَ طَلَاقُهُ بِشَيْ‏ءٍ .
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Musa ibn Bakr from Zurarah who has said the following: “Abu Ja‘far , has stated this Hadith. ‘Divorce must take place in the presence of two men as well as one’s going back to his divorced wife. If he is ignorant (of the need for witness) and goes to bed with his wife, he must also appoint witness for what has happened; she still is his wife. If he had not done (pronounced divorce) in the presence of witnesses, his divorce as such does not have any valid effect.’”
