Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 12
أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« فِي طِينِ اَلْمَطَرِ إِنَّهُ لاَ بَأْسَ بِهِ أَنْ يُصِيبَ اَلثَّوْبَ ثَلاَثَةَ أَيَّامٍ إِلاَّ أَنْ يُعْلَمَ أَنَّهُ قَدْ نَجَّسَهُ شَيْءٌ بَعْدَ اَلْمَطَرِ وَ إِنْ أَصَابَهُ بَعْدَ ثَلاَثَةِ أَيَّامٍ فَاغْسِلْهُ وَ إِنْ كَانَ اَلطَّرِيقُ نَظِيفاً لَمْ تَغْسِلْهُ».
Ahmad ibn Muhammad narrated from Muhammad ibn Isma'il, from some of our companions, from Abu Al-Hasan عليه السلام.
Imam عليه السلام said: "Regarding the mud from rain, there is no harm if it soils the garment for three days, unless it is known that something has contaminated it with impurity after the rain. However, if it comes in contact with the garment after three days, then wash it. If the path is clean, then you do not need to wash it."
