عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى أَوِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ قَالَ قُلْتُ لِأَبِي جَعْفَرٍ ( عليه السلام ) رَجُلٌ كَتَبَ بِطَلَاقِ امْرَأَتِهِ أَوْ بِعِتْقِ غُلَامِهِ ثُمَّ بَدَا لَهُ فَمَحَاهُ قَالَ لَيْسَ ذَلِكَ بِطَلَاقٍ وَ لَا عَتَاقٍ حَتَّى يَتَكَلَّمَ بِهِ .
2. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa or Ibn Abi ‘Umayr from ibn ‘Udhaynah from Zurarah who has said the following: “I once asked abu Ja‘far , about the case of a man who divorces his wife in writing or sets free his slave; he then changes his mind and deletes it. He (the Imam) said, ‘It is not a divorce or setting free of a slave until he pronounces it through his mouth.’”
