163 - 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.
Hadith.163 - Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim 
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.'.
