[Machine] That the Prophet ﷺ said, "If water is two qullah, nothing will impure it except what overpowers its smell or taste. This is how I have found it, and the word 'two qullah' in it is strange."  

البيهقي:١٢٢٧وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أنا أَبُو الْوَلِيدِ الْفَقِيهُ ثنا جَعْفَرٌ الْحَافِظُ ثنا أَبُو الْأَزْهَرِ فَذَكَرَهُ بِإِسْنَادِهِ مِثْلَهُ

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا كَانَ الْمَاءُ قُلَّتَيْنِ لَمْ يُنَجِّسْهُ شَيْءٌ إِلَّا مَا غَلَبَهُ رِيحُهُ أَوْ طَعْمُهُ كَذَا وَجَدْتُهُ وَلَفْظُ قُلَّتَيْنِ فِيهِ غَرِيبٌ
