٤ـ مُحَمَّدُ بْنُ يَحْيَى رَفَعَهُ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ لاَ يُفْسِدُ الْمَاءَ إِلاَّ مَا كَانَ لَهُ نَفْسٌ سَائِلَةٌ.
4. Muhammad ibn Yahya in a marfu‘ manner has narrated the following: “Abu ‘Abd Allah , has said, ‘Water does not become polluted because of the living things which do not have spurting blood when a cut is made in its body.’”
