Chapter on Water and Its Rules
Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 21
وَ سَأَلَ يَعْقُوبُ بْنُ عُثَيْمٍ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فَقَالَ لَهُ: بِئْرُ مَاءٍ فِي مَائِهَا رِيحٌ يُخْرَجُ مِنْهَا قِطَعُ جُلُودٍ فَقَالَ «لَيْسَ بِشَيْءٍ إِنَّ اَلْوَزَغَ رُبَّمَا طَرَحَ جِلْدَهُ إِنَّمَا يَكْفِيكَ مِنْ ذَلِكَ دَلْوٌ وَاحِدٌ».
Ya’qub ibn Uthaym asked Abu Abdullah عليه السلام about a well of water that has an odour, and pieces of skin are found in it. Imam عليه السلام said: "It is nothing (to worry about). Sometimes a lizard sheds its skin. All that is required is to draw one bucket of water from it."
