١٠ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ أَبِي الأعَزِّ النَّخَّاسِ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) إِنِّي أُعَالِجُ الدَّوَابَّ فَرُبَّمَا خَرَجْتُ بِاللَّيْلِ وَقَدْ بَالَتْ وَرَاثَتْ فَيَضْرِبُ أَحَدُهَا بِرِجْلِهِ أَوْ يَدِهِ فَيَنْضِحُ عَلَى ثِيَابِي فَأُصْبِحُ فَأَرَى أَثَرَهُ فِيهِ فَقَالَ لَيْسَ عَلَيْكَ شَيْ‏ءٌ. 
10. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Ali ibn al-Hakam from abu al-‘Aziz al-Nakhkhas who has said the following: “I once said to abu ‘Abd Allah , ‘I deal with animals. Some times I go out during the night, and animals may have urinated and dunged and they spread it with their legs which pollutes my clothes; and in the morning I find the marks.’ He (the Imam) said, ‘You are not required to do anything.’”
