عَلِيٌّ عَنْ أَبِيهِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ أَبِي الْحَسَنِ الرِّضَا ( عليه السلام ) قَالَ سُئِلَ عَنْ رَجُلٍ طَهُرَتِ امْرَأَتُهُ مِنْ حَيْضِهَا فَقَالَ فُلَانَةُ طَالِقٌ وَ قَوْمٌ يَسْمَعُونَ كَلَامَهُ وَ لَمْ يَقُلْ لَهُمُ اشْهَدُوا أَ يَقَعُ الطَّلَاقُ عَلَيْهَا قَالَ نَعَمْ هَذِهِ شَهَادَةٌ .
4. Ali ibn Ibrahim has narrated from his father from Safwan ibn Yahya who has said the following: “Abu al-Hassan, al-Rida’ , was asked about the case of a man whose wife becomes clean of Hayd (menses) and he says this: ‘So and so is ‘Taliq’ (let go, divorced) and a people hears his statement but he does not ask them to bear witness: if divorce takes place or not, he (the Imam) said, ‘Yes, is bearing witness.’”
