عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ الزَّيَّاتِ قَالَ قُلْتُ لِأَبِي الْحَسَنِ ( عليه السلام ) إِنِّي ظَاهَرْتُ مِنِ امْرَأَتِي فَقَالَ كَيْفَ قُلْتَ قَالَ قُلْتُ أَنْتِ عَلَيَّ كَظَهْرِ أُمِّي إِنْ فَعَلْتِ كَذَا وَ كَذَا فَقَالَ لَا شَيْءَ عَلَيْكَ وَ لَا تَعُدْ .
24. A number of our people have narrated from Sahl ibn Ziyad from al-Qasim ibn Muhammad al-Zayyat who has said the following: “I once said to abu ‘Abd Allah (a.s.), ‘I have expressed the statement of al-Zihar about my wife.’ He (the Imam) asked, ’How did you say it?’ I replied that it was, ‘You are like the back of my mother to me if you did so and so.’ He (the Imam) said, ‘It does not have any valid effect but you must not repeat it again.’”
