Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 20
عَنْهُ عَنْ أَحْمَدَ عَنِ اَلْحُسَيْنِ عَنِ اَلْحَسَنِ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ: سَأَلْتُهُ عَنْ رَجُلٍ يَكُونُ فِي فَلاَةٍ مِنَ اَلْأَرْضِ فَأَجْنَبَ وَ لَيْسَ عَلَيْهِ إِلاَّ ثَوْبٌ فَأَجْنَبَ فِيهِ وَ لَيْسَ يَجِدُ اَلْمَاءَ قَالَ« يَتَيَمَّمُ وَ يُصَلِّي عُرْيَاناً قَائِماً يُومِئُ إِيمَاءً».
From him, from Ahmad, from Al-Husayn, from Al-Hasan, from Zur’ah, from Sama’ah, who said:
I asked Imam عليه السلام about a man who is in a desert and becomes junub (in a state of major ritual impurity) while having only one garment, and he becomes junub in it and does not find water. Imam عليه السلام said: "He should perform tayammum (dry ablution) and pray while naked, standing, and gesturing (for bowing and prostration)."
