"I passed by the Prophet ﷺ when he was performing Wudu' from the well of Buda'ah. I said: 'Are you performing Wudu' from it when garbage is thrown into it?' He said: 'Water is not made impure by anything.'"
مَرَرْتُ بِالنَّبِيِّ ﷺ وَهُوَ يَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ فَقُلْتُ أَتَتَوَضَّأُ مِنْهَا وَهِيَ يُطْرَحُ فِيهَا مَا يُكْرَهُ مِنَ النَّتْنِ فَقَالَ الْمَاءُ لاَ يُنَجِّسُهُ شَىْءٌ
