٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ أَبِي الْحَسَنِ (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ طَافَ بِالْبَيْتِ وَهُوَ جُنُبٌ فَذَكَرَ وَهُوَ فِي الطَّوَافِ قَالَ يَقْطَعُ طَوَافَهُ وَلا يَعْتَدُّ بِشَيْ‏ءٍ مِمَّا طَافَ وَسَأَلْتُهُ عَنْ رَجُلٍ طَافَ ثُمَّ ذَكَرَ أَنَّهُ عَلَى غَيْرِ وُضُوءٍ قَالَ يَقْطَعُ طَوَافَهُ وَلا يَعْتَدُّ بِهِ. 
4. Muhammad ibn Yahya has narrated from al-‘Amrakiy ibn Ali from Ali ibn Ja’far who has said the following: “I once asked abu al-Hassan , about a man who performs Tawaf around the House when he is involved in sexual relation (because of which Ghusl (bath) is obligatory), but remembers when he is in Tawaf. He (the Imam) said, ‘He must discontinue his Tawaf and you must not consider it valid.’ I then asked him (the Imam) about a man who performs Tawaf and then remembers that he is without wudu’. He (the Imam) said, ‘He must discontinue and it (Tawaf) is not acceptable.’”
