Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 8
فَأَخْبَرَنِي الشَّيْخُ أَيَّدَهُ اللَّهُ تَعَالَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ سَعْدِ بْنِ عَبْدِ اللَّهِ عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ وَمُحَمَّدِ بْنِ عِيسَى وَمُوسَى بْنِ عُمَرَ بْنِ يَزِيدَ الصَّيْقَلِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ أَبِي الْحَسَنِ الرِّضَا عَلَيْهِ السَّلَامُ فِي الرَّجُلِ تُصِيبُهُ الْجَنَابَةُ وَبِهِ قُرُوحٌ أَوْ جُرُوحٌ أَوْ يَكُونُ يَخَافُ عَلَى نَفْسِهِ الْبَرْدَ، قَالَ: لَا يَغْتَسِلُ، يَتَيَمَّمُ.
Ahmad ibn Muhammad narrated from his father, from Sa‘d ibn ‘Abdullah, from Muhammad ibn al-Husayn, Muhammad ibn ‘Isa, and Musa ibn ‘Umar ibn Yazid al-Sayqal, from Ahmad ibn Muhammad ibn Abi Nasr:
Abu al-Hasan al-Ridha عليه السلام was asked regarding a man who becomes in a state of janabah and has sores, wounds, or fears the cold for his life. Imam عليه السلام said: "He should not perform ghusl; he should perform tayammum."
