٥ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنِ الْمُعَلَّى بْنِ خُنَيْسٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْخِنْزِيرِ يَخْرُجُ مِنَ الْمَاءِ فَيَمُرُّ عَلَى الطَّرِيقِ فَيَسِيلُ مِنْهُ الْمَاءُ أَمُرُّ عَلَيْهِ حَافِياً فَقَالَ أَ لَيْسَ وَرَاءَهُ شَيْ‏ءٌ جَافٌّ قُلْتُ بَلَى قَالَ فَلاَ بَأْسَ إِنَّ الأرْضَ تُطَهِّرُ بَعْضُهَا بَعْضاً. 
5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Jamil ibn Darraj from al-Mu‘alla’ ibn Khunays who has said the following: “I once asked abu ‘Abd Allah , about the swine which comes out of water and passes on the road while water falls from it. What happens if I walk bare foot over such areas? He (the Imam) asked. ‘Are not there certain dry spots behind it?’ I replied, ‘Yes, there are such spots.’ He (the Imam) said, ‘It is not harmful. Certain parts of earth cleanse other parts.’”
