"It was said: 'O Messenger of Allah, you perform Wudu' from the well into which the bodies of dogs, menstrual rags and garbage are thrown?' He said: 'Water is pure and it is not made impure by anything.'"  

قِيلَ يَا رَسُولَ اللَّهِ أَتَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُطْرَحُ فِيهَا لُحُومُ الْكِلاَبِ وَالْحِيَضُ وَالنَّتَنُ فَقَالَ الْمَاءُ طَهُورٌ لاَ يُنَجِّسُهُ شَىْءٌ  

The people asked the Messenger of Allah ﷺ: Can we perform ablution out of the well of Buda'ah, which is a well into which menstrual clothes, dead dogs and stinking things were thrown? He replied: Water is pure and is not defiled by anything.  

أَنَّهُ قِيلَ لِرَسُولِ اللَّهِ ﷺ أَنَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُطْرَحُ فِيهَا الْحِيَضُ وَلَحْمُ الْكِلاَبِ وَالنَّتْنُ فَقَالَ رَسُولُ اللَّهِ ﷺ الْمَاءُ طَهُورٌ لاَ يُنَجِّسُهُ شَىْءٌ  

I heard that the people asked the Prophet of Allah ﷺ: Water is brought for you from the well of Buda'ah. It is a well in which dead dogs, menstrual clothes and excrement of people are thrown. The Messenger of Allah ﷺ replied: Verily water is pure and is not defiled by anything. Abu Dawud said I heard Qutaibah b. Sa'id say: I asked the person in charge of the well of Bud'ah about the depth of the well. He replied: At most the water reaches pubes. Then I asked: Where does it reach when its level goes down ? He replied: Below the private part of the body. Abu Dawud said: I measured the breadth of the well of Buda'ah with my sheet which I stretched over it. I them measured it with the hand. It measured six cubits in breadth. I then asked the man who opened the door of garden for me and admitted me to it: Has the condition of this well changed from what it had originally been in the past ? He replied: No. I saw the color of water in this well had changed.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ يُقَالُ لَهُ إِنَّهُ يُسْتَقَى لَكَ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُلْقَى فِيهَا لُحُومُ الْكِلاَبِ وَالْمَحَايِضُ وَعَذِرُ النَّاسِ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْمَاءَ طَهُورٌ لاَ يُنَجِّسُهُ شَىْءٌ  

"It was said, 'O Messenger of Allah! Shall we use the water of Buda'ah well to perform ablution while it is a well in which menstruation rags, flesh of dogs and the putrid are dumped?" Messenger of Allah said: 'Indeed water is pure, nothing makes it impure.'"  

قِيلَ يَا رَسُولَ اللَّهِ أَنَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُلْقَى فِيهَا الْحِيَضُ وَلُحُومُ الْكِلاَبِ وَالنَّتْنُ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْمَاءَ طَهُورٌ لاَ يُنَجِّسُهُ شَيْءٌ  

"It was said: 'O Messenger of Allah, you perform Wudu' from the well into which the bodies of dogs, menstrual rags and garbage are thrown?' He said: 'Water is pure and it is not made impure by anything.'" (Using translation from Nasāʾī 326)   

أَنَّهُ قِيلَ لِرَسُولِ اللهِ ﷺ يَا رَسُولَ اللهِ أَتَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُطْرَحُ فِيهَا الْمَحِيضُ وَلُحُومُ الْكِلَابِ وَالنَّتْنُ؟ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّ الْمَاءَ طَهُورٌ لَا يُنَجِّسُهُ شَيْءٌ  

"It was said, 'O Messenger of Allah! Shall we use the water of Buda'ah well to perform ablution while it is a well in which menstruation rags, flesh of dogs and the putrid are dumped?" Messenger of Allah said: 'Indeed water is pure, nothing makes it impure.'" (Using translation from Tirmidhī 66)  

قِيلَ يَا رَسُولَ اللهِ أَنَتَوَضَّأُ مِنْ بِئْرِ بُضَاعَةَ وَهِيَ بِئْرٌ يُلْقَى فِيهَا الْحِيَضُ وَالنَّتْنُ وَلُحُومُ الْكِلَابِ؟ قَالَ الْمَاءُ طَهُورٌ لَا يُنَجِّسُهُ شَيْءٌ  

"قِيلَ يَا رَسُولَ الله: أَنَتَوضَّأُ مِنْ بِئر بضاعَة؟ وَهِىَ بِئْرٌ يُلْقَى فِيهَا الْحَيْضُ وَلُحُوم الكِلَابِ والنتن؟ فَقَالَ رَسُولُ الله ﷺ الْمَاءُ طَهُورٌ وَلَا يُنَجِّسه شَىْءٌ".
