Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 21
فَأَمَّا مَا رَوَاهُ مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنِ اَلْعَبَّاسِ عَنْ عَبْدِ اَللَّهِ بْنِ اَلْمُغِيرَةِ عَنْ بَعْضِ أَصْحَابِهِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا كَانَ اَلْمَاءُ قَدْرَ قُلَّتَيْنِ لَمْ يُنَجِّسْهُ شَيْءٌ وَ اَلْقُلَّتَانِ جَرَّتَانِ».
As for what was narrated by Muhammad ibn Ali ibn Mahbub, from Al-Abbas, from Abdullah ibn Al-Mughira, from some of our companions, from Abu Abdullah عليه السلام:
Imam عليه السلام said: "If the water is equal to two qullahs (large jars), nothing renders it impure. The two qullahs are two large jars."
