١١ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْعَذِرَةِ تَقَعُ فِي الْبِئْرِ قَالَ يُنْزَحُ مِنْهَا عَشَرَةُ دِلاَءٍ فَإِنْ ذَابَتْ فَأَرْبَعُونَ أَوْ خَمْسُونَ دَلْواً.
11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah who has said the following: “I once asked abu ‘Abd Allah, Alayhi al-Salam, about the falling of feces into a well. He (the Imam) said, ‘Ten buckets of water must be taken out and if it has disintegrated then forty or fifty buckets of water must be taken out.’”
