The Chapter on Tayammum (Dry Ablution)
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 22
وَ سَأَلَ مُحَمَّدُ بْنُ مُسْلِمٍ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يَكُونُ بِهِ اَلْقُرُوحُ وَ اَلْجِرَاحَاتُ فَيُجْنِبُ فَقَالَ «لاَ بَأْسَ بِأَنْ يَتَيَمَّمَ وَ لاَ يَغْتَسِلَ.
Muhammad ibn Muslim asked Imam Muhammad ibn Ali Al-Baqir عليه السلام about a man who has sores and wounds and becomes junub (ritually impure due to sexual discharge). Imam عليه السلام said: 'There is no harm if he performs tayammum and does not make ghusl (ritual bath).'
