٢ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْمَاءِ الَّذِي تَبُولُ فِيهِ الدَّوَابُّ وَتَلَغُ فِيهِ الْكِلاَبُ وَيَغْتَسِلُ فِيهِ الْجُنُبُ قَالَ إِذَا كَانَ الْمَاءُ قَدْرَ كُرٍّ لَمْ يُنَجِّسْهُ شَيْ‏ءٌ.
2. A number of our people have narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn al-Hakam from abu Ayyub al-Khazzaz from Muhammad ibn Muslim who has said the following: “I once asked abu ‘Abd Allah , about a water which dogs lick and in which animals urinate and people take baths after sexual activities. He (the Imam) said, ‘If its quantity is one Kur, then such things cannot make it unclean.’”
