What Defiles Clothing and the Body
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 17
وَقَالَ أَبُو اَلْحَسَنِ مُوسَى بْنُ جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: فِي طِينِ اَلْمَطَرِ «إِنَّهُ لاَ بَأْسَ بِهِ أَنْ يُصِيبَ اَلثَّوْبَ ثَلاَثَةَ أَيَّامٍ إِلاَّ أَنْ يَعْلَمَ أَنَّهُ قَدْ نَجَّسَهُ شَيْءٌ بَعْدَ اَلْمَطَرِ فَإِنْ أَصَابَهُ بَعْدَ ثَلاَثَةِ أَيَّامٍ غَسَلَهُ وَ إِنْ كَانَ طَرِيقاً نَظِيفاً لَمْ يَغْسِلْهُ.
Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim عليه السلام said regarding rain-soaked mud: 'There is no harm if it comes into contact with clothing for three days, unless it is known that it has become contaminated with something impure after the rain. If it comes into contact after three days, it should be washed. However, if it is a clean path, there is no need to wash it.'.
