2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ قَالَ سَمِعْتُ صَفْوَانَ بْنَ يَحْيَى يَقُولُ قُلْتُ لِلرِّضَا (عَلَيْهِ السَّلام) إِنَّ رَجُلا مِنْ مَوَالِيكَ أَمَرَنِي أَنْ أَسْأَلَكَ عَنْ مَسْأَلَةٍ هَابَكَ وَاسْتَحْيَا مِنْكَ أَنْ يَسْأَلَكَ قَالَ وَمَا هِيَ قُلْتُ الرَّجُلُ يَأْتِي امْرَأَتَهُ فِي دُبُرِهَا قَالَ ذَلِكَ لَهُ قَالَ قُلْتُ لَهُ فَأَنْتَ تَفْعَلُ قَالَ إِنَّا لا نَفْعَلُ ذَلِكَ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from who has said, ‘I heard Safwan ibn Yahya who has said the following: “I once said to al-Rida’ عليه السلام, that one of his followers has asked me to ask you a question in which he feels shy and intimidated. He (the Imam) asked, ‘What is the question?’ I asked, ‘Can a man come to his wife in her anus?’ He (the Imam) said, ‘It is up to him.’ I then asked, ‘Do you do so?’ He (the Imam) said, ‘No, we do not do so.’”
