مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلَاءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا ( عليهما السلام ) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ طَلَّقَ امْرَأَتَهُ وَاحِدَةً قَالَ هُوَ أَمْلَكُ بِرَجْعَتِهَا مَا لَمْ تَنْقَضِ الْعِدَّةُ قُلْتُ فَإِنْ لَمْ يُشْهِدْ عَلَى رَجْعَتِهَا قَالَ فَلْيُشْهِدْ قُلْتُ فَإِنْ غَفَلَ عَنْ ذَلِكَ قَالَ فَلْيُشْهِدْ حِينَ يَذْكُرُ وَ إِنَّمَا جُعِلَ الشُّهُودُ لِمَكَانِ الْمِيرَاثِ .
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad Ali ibn al-Hakam from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, (abu Ja‘far or abu ‘Abd Allah), ‘Alayhim al-Salam, about the case of a man who divorces his wife once. He (the Imam) said, ‘He has the authority to go back to her before the expiration of waiting period.’ I then asked about if he does not arrange witnesses to his going back. He (the Imam) said, ‘He must do so.’ I then asked, ‘What happens if he is not attentive to it?’ He (the Imam) said, ‘He must find witness when he remembers; witness is because of inheritance.’”
