The Sufficient (Vol 3) · Hadith 22 (#Ḥadīth #2)
Chapter 4 | The Case of a Well and Things that May Fall in It (Fatwa best explains Ahadith 2-12 as well as the following chapter.)
2ـ وَبِهَذَا الإِسْنَادِ قَالَ مَاءُ الْبِئْرِ وَاسِعٌ لاَ يُفْسِدُهُ شَيْءٌ إِلاَّ أَنْ يَتَغَيَّرَ بِهِ.
2. Through the same chain of narrators as the previous Hadith the following is stated: “He (the Imam) ‘Alayhi al-Salam, said, ‘Well water is vast. It does not become polluted until it is changed.’”
