Sunan an-Nasai
أَخْبَرَنَا الْعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ، قَالَ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُسْلِمٍ، - وَكَانَ مِنَ الْعَابِدِينَ - عَنْ مُطَرِّفِ بْنِ طَرِيفٍ، عَنْ خَالِدِ بْنِ أَبِي نَوْفٍ، عَنْ سَلِيطٍ، عَنِ ابْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنْ أَبِيهِ، قَالَ مَرَرْتُ بِالنَّبِيِّ صلى الله عليه وسلم وَهُوَ يَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ فَقُلْتُ أَتَتَوَضَّأُ مِنْهَا وَهِيَ يُطْرَحُ فِيهَا مَا يُكْرَهُ مِنَ النَّتْنِ فَقَالَ " الْمَاءُ لاَ يُنَجِّسُهُ شَىْءٌ " .
It was narrated from Ibn Abi Sa'eed Al-Khudri that his father said: "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.'"
