Water; Its Purity and Impurity
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ عَنْ جُلُودِ اَلْمَيْتَةِ يُجْعَلُ فِيهَا اَللَّبَنُ وَ اَلْمَاءُ وَ اَلسَّمْنُ مَا تَرَى فِيهِ فَقَالَ «لاَ بَأْسَ بِأَنْ تَجْعَلَ فِيهَا مَا شِئْتَ مِنْ مَاءٍ أَوْ لَبَنٍ أَوْ سَمْنٍ وَ تَتَوَضَّأَ مِنْهُ وَ تَشْرَبَ وَ لَكِنْ لاَ تُصَلِّ فِيهَا.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about the skins of dead animals used to hold milk, water, or clarified butter. Imam عليه السلام said: "There is no harm in putting whatever you like in them—water, milk, or clarified butter—and using it for ablution and drinking. However, do not pray in it (i.e., in clothes made from it)”.
