Water; Its Purity and Impurity
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ عَنْ مَاءٍ شَرِبَتْ مِنْهُ دَجَاجَةٌ فَقَالَ «إِنْ كَانَ فِي مِنْقَارِهَا قَذَرٌ لَمْ يُتَوَضَّأْ مِنْهُ وَ لَمْ تَشْرَبْ وَ إِنْ لَمْ يُعْلَمْ فِي مِنْقَارِهَا قَذَرٌ تَوَضَّأْ مِنْهُ وَ اِشْرَبْ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about water from which a chicken had drunk. Imam عليه السلام said: "If there is known dirt on its beak, do not perform ablution with it or drink from it. But if there is no known dirt on its beak, you may perform ablution with it and drink from it."
