Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 21
وَ رَوَى إِسْحَاقُ بْنُ عَمَّارٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَنَّ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ كَانَ يَقُولُ:« لاَ بَأْسَ بِسُؤْرِ اَلْفَأْرَةِ إِذَا شَرِبَتْ مِنَ اَلْإِنَاءِ أَنْ يُشْرَبَ مِنْهُ وَ يُتَوَضَّأَ مِنْهُ».
Ishaq ibn Ammar narrated from Abu Abdullah عليه السلام that Abu Ja’far عليه السلام used to say: "There is no harm in the leftover water of a mouse if it drinks from a container. It is permissible to drink from it and to perform wudu (ablution) with it."
