Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 8
وَرَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ: سَأَلْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْجُنُبِ تَكُونُ بِهِ اَلْقُرُوحُ قَالَ« لاَ بَأْسَ بِأَنْ لاَ يَغْتَسِلَ يَتَيَمَّمُ».
Al-Hasan ibn Mahbub narrated from Abu Ayyub, from Muhammad ibn Muslim, who said:
I asked Abu Ja’far عليه السلام about a person in a state of janaba (ritual impurity) who has sores. Imam عليه السلام said: "There is no harm if he does not perform ghusl; he should perform tayammum."
