12 - وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: فِي اَلْمَاءِ اَلَّذِي تَبُولُ فِيهِ اَلدَّوَابُّ وَ تَلَغُ فِيهِ اَلْكِلاَبُ وَ يَغْتَسِلُ فِيهِ اَلْجُنُبُ «إِنَّهُ إِذَا كَانَ قَدْرَ كُرٍّ لَمْ يُنَجِّسْهُ شَيْءٌ.
Hadith.12 - Imam Jafar ibn Muhammad Al-Sadiq 
said:
"Regarding water into which animals urinate, dogs drink, or someone performs ghusl (ritual washing after major impurity): "If it reaches the amount of a kurr (a specific measure), then nothing can make it impure”.
