Water; Its Purity and Impurity
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «كَانَتْ فِي اَلْمَدِينَةِ بِئْرٌ فِي وَسَطِ مَزْبَلَةٍ فَكَانَتِ اَلرِّيحُ تَهُبُّ فَتُلْقِي فِيهَا اَلْقَذَرَ وَ كَانَ اَلنَّبِيُّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ يَتَوَضَّأُ مِنْهَا.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "There was a well in Medina in the middle of a garbage dump. The wind would blow filth into it, yet The Prophet صلى الله عليه وعلى آله وسلم used to perform ablution from it."
