سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِي طَالِبٍ عَبْدِ اَللَّهِ بْنِ اَلصَّلْتِ عَنْ عَبْدِ اَللَّهِ بْنِ اَلْمُغِيرَةِ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلْفَأْرَةِ تَقَعُ فِي اَلْبِئْرِ فَيَتَوَضَّأُ اَلرَّجُلُ مِنْهَا وَ يُصَلِّي وَ هُوَ لاَ يَعْلَمُ أَ يُعِيدُ اَلصَّلاَةَ وَ يَغْسِلُ ثَوْبَهُ فَقَالَ« لاَ يُعِيدُ اَلصَّلاَةَ وَ لاَ يَغْسِلُ ثَوْبَهُ».
Sa'd ibn Abdullah narrated from Ahmad ibn Muhammad, from Abu Talib Abdullah ibn al-Salt, from Abdullah ibn al-Mughirah, from Mu'awiyah ibn Ammar:
Abu Abdullah عليه السلام was asked regarding a mouse that falls into a well and a person performs Wudu' (ablution) from it and prays without knowing (about the mouse). Should he repeat the prayer and wash his garment? Imam عليه السلام said: "He does not need to repeat the prayer or wash his garment."
