Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 17
وَ سَأَلَ زَيْدٌ اَلشَّحَّامُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلثَّوْبِ يَكُونُ فِيهِ اَلْجَنَابَةُ وَ تُصِيبُنِي اَلسَّمَاءُ حَتَّى يَبْتَلَّ عَلَيَّ فَقَالَ «لاَ بَأْسَ بِهِ.
Zayd al-Shahham asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام about a garment that has janabah (ritual impurity due to seminal discharge) and is then rained on, causing it to become wet while he is wearing it. Imam عليه السلام said: 'There is no harm in it.'
