3ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ صَفْوَانَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ مُحَمَّدٍ الْحَلَبِيِّ قَالَ نَزَلْنَا فِي مَكَانٍ بَيْنَنَا وَبَيْنَ الْمَسْجِدِ زُقَاقٌ قَذَرٌ فَدَخَلْتُ عَلَى أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فَقَالَ أَيْنَ نَزَلْتُمْ فَقُلْتُ نَزَلْنَا فِي دَارِ فُلاَنٍ فَقَالَ إِنَّ بَيْنَكُمْ وَبَيْنَ الْمَسْجِدِ زُقَاقاً قَذَراً أَوْ قُلْنَا لَهُ إِنَّ بَيْنَنَا وَبَيْنَ الْمَسْجِدِ زُقَاقاً قَذَراً فَقَالَ لاَ بَأْسَ الأرْضُ تُطَهِّرُ بَعْضُهَا بَعْضاً قُلْتُ وَالسِّرْقِينُ الرَّطْبُ أَطَأُ عَلَيْهِ فَقَالَ لاَ يَضُرُّكَ مِثْلُهُ.
3. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan from Ishaq ibn ‘Ammar from Muhammad al-Halabiy who has said the following: “Once we found lodging in a place. Between this place and the Masjid there were dirty passageways. I visited abu ‘Abd Allah (a.s.). He (the Imam) asked, ‘Where have you found lodging?’ I replied, ‘It is the house of so and so.’ He (the Imam) or we said, ‘Between that house and Masjid there are unclean passageways.’ He (the Imam) said, ‘It is not harmful, certain parts of earth cleanse other parts.’ I (the narrator) asked, ‘What happens if I step on wet dung?’ He (the Imam) said, ‘Such things are not harmful.’”
