Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 11
أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ اَلْحَكَمِ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سُئِلَ عَنِ اَلْفَأْرَةِ تَقَعُ فِي اَلْبِئْرِ لاَ يُعْلَمُ بِهَا إِلاَّ بَعْدَ مَا يُتَوَضَّأُ مِنْهَا أَ يُعَادُ اَلْوُضُوءُ فَقَالَ« لاَ».
Ahmad ibn Muhammad narrated from Ali ibn al-Hakam, from Aban ibn Uthman:
Abu Abdullah عليه السلام was asked: "If a mouse falls into a well and it is not known until after Wudu' (ablution) has been performed from it, should the Wudu' be repeated?" Imam عليه السلام said: "No."
