سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ اَلْحَسَنِ عَنْ عَمْرِو بْنِ سَعِيدٍ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارٍ قَالَ: سُئِلَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْبِئْرِ يَقَعُ فِيهَا زِنْبِيلُ عَذِرَةٍ يَابِسَةٍ أَوْ رَطْبَةٍ فَقَالَ« لاَ بَأْسَ بِهِ إِذَا كَانَ فِيهَا مَاءٌ كَثِيرٌ
Sa’d ibn Abdullah, from Ahmad ibn Al-Hasan, from Amr ibn Sa’id, from Musaddiq ibn Sadaqah, from Ammar, who said:
Abu Abdullah عليه السلام was asked about a well into which a basket of feces, whether dry or moist, falls. Imam عليه السلام said: "There is no harm if there is a large amount of water in it."
