Chapter on Purifying Water From Impurities
Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 11
وَرُوِيَ عَنْ الْقَاسِمِ عَنْ أَبَانَ عَنْ أَبِي الْعَبَّاسِ الْفَضْلِ الْبَقْبَاقِ قَالَ: قَالَ أَبُو عَبْدِ اللهِ عَلَيْهِ السَّلَامُ: فِي الْبِئْرِ يَقَعُ فِيهَا الْفَأْرَةُ أَوِ الدَّابَّةُ أَوِ الْكَلْبُ أَوِ الطَّيْرُ فَيَمُوتُ، قَالَ: يُخْرَجُ، ثُمَّ يُنْزَحُ مِنَ الْبِئْرِ دِلَاءٌ، ثُمَّ يُشْرَبُ مِنْهُ وَيُتَوَضَّأُ.
It is narrated from Al-Qasim, from Aban, from Abu Al-Abbas Al-Fadl Al-Baqbaq, who said:
Abu Abdullah عليه السلام said regarding a well into which a mouse, an animal, a dog, or a bird falls and dies: "It should be removed, then buckets of water should be drawn from the well, after which it may be drunk from and used for ablution."
