Water; Its Purity and Impurity
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ رُوِيَ عَنْ أَبِي بَصِيرٍ أَنَّهُ قَالَ: نَزَلْنَا فِي دَارٍ فِيهَا بِئْرٌ إِلَى جَنْبِهَا بَالُوعَةٌ لَيْسَ بَيْنَهُمَا إِلاَّ نَحْوٌ مِنْ ذِرَاعَيْنِ فَامْتَنَعُوا مِنَ اَلْوُضُوءِ مِنْهَا فَشَقَّ ذَلِكَ عَلَيْهِمْ فَدَخَلْنَا عَلَى أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فَأَخْبَرْنَاهُ فَقَالَ «تَوَضَّئُوا مِنْهَا فَإِنَّ لِتِلْكَ اَلْبَالُوعَةِ مَجَارِيَ تُصَبُّ فِي وَادٍ يَنْصَبُّ فِي اَلْبَحْرِ.
It was narrated from Abu Basir that Imam عليه السلام said: "We stayed in a house with a well beside a drain, with only about two arm-lengths between them. The people refrained from performing ablution from it, which caused them difficulty. So we went to Abu Abdullah عليه السلام and informed him. Imam عليه السلام said: 'Perform ablution from it, for that drain has channels that flow into a valley, which leads to the sea.'".
