Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ سَأَلَ عَمَّارُ بْنُ مُوسَى اَلسَّابَاطِيُّ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَجِدُ فِي إِنَائِهِ فَأْرَةً وَ قَدْ تَوَضَّأَ مِنْ ذَلِكَ اَلْإِنَاءِ مِرَاراً وَ اِغْتَسَلَ مِنْهُ أَوْ غَسَلَ ثِيَابَهُ وَ قَدْ كَانَتِ اَلْفَأْرَةُ مُنْسَلِخَةً فَقَالَ «إِنْ كَانَ رَآهَا فِي اَلْإِنَاءِ قَبْلَ أَنْ يَغْتَسِلَ أَوْ يَتَوَضَّأَ أَوْ يَغْسِلَ ثِيَابَهُ ثُمَّ فَعَلَ ذَلِكَ بَعْدَ مَا رَآهَا فِي اَلْإِنَاءِ فَعَلَيْهِ أَنْ يَغْسِلَ ثِيَابَهُ وَ يَغْسِلَ كُلَّ مَا أَصَابَهُ ذَلِكَ اَلْمَاءُ وَ يُعِيدَ اَلْوُضُوءَ وَ اَلصَّلاَةَ وَ إِنْ كَانَ إِنَّمَا رَآهَا بَعْدَ مَا فَرَغَ مِنْ ذَلِكَ وَ فِعْلِهِ فَلاَ يَمَسَّ مِنَ اَلْمَاءِ شَيْئاً وَ لَيْسَ عَلَيْهِ شَيْءٌ لِأَنَّهُ لاَ يَعْلَمُ مَتَى سَقَطَتْ فِيهِ» ثُمَّ قَالَ «لَعَلَّهُ أَنْ يَكُونَ إِنَّمَا سَقَطَتْ فِيهِ تِلْكَ اَلسَّاعَةَ اَلَّتِي رَآهَا.
Ammar ibn Musa al-Sabati asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام about a man who finds a dead mouse in his container after having used it multiple times for ablution, ghusl (ritual washing), or washing his clothes. The mouse was already decayed. Imam عليه السلام said: "If he saw it in the container before performing ablution, ghusl, or washing his clothes, and still used the water afterward, then he must wash his clothes, wash everything that came into contact with that water, and repeat his ablution and prayer. However, if he only noticed the mouse after he had finished, then he should avoid using the water, but he is not required to repeat anything, as he does not know when it fell into the container." Imam عليه السلام said: "It is possible that it only fell into the container at the moment he saw it."
