Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 5
عَنْهُ عَنِ اَلْحُسَيْنِ بْنِ اَلنَّضْرِ اَلْأَرْمَنِيِّ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ اَلْقَوْمُ يَكُونُونَ فِي اَلسَّفَرِ فَيَمُوتُ مِنْهُمْ مَيِّتٌ وَ مَعَهُمْ جُنُبٌ وَ مَعَهُمْ مَاءٌ قَلِيلٌ قَدْرَ مَا يَكْفِي أَحَدَهُمَا أَيُّهُمَا يَبْدَأُ بِهِ قَالَ« يَغْتَسِلُ اَلْجُنُبُ وَ يُتْرَكُ اَلْمَيِّتُ لِأَنَّ هَذَا فَرِيضَةٌ وَ هَذَا سُنَّةٌ».
From him, from al-Husayn ibn al-Nadr al-Armani, who said:
I asked Abu al-Hasan al-Ridha عليه السلام: 'A group of people are traveling, and one of them dies while another is in a state of janabah. They have a small amount of water, just enough for one of them. Which one takes precedence in using it?' Imam عليه السلام said: 'The one in a state of janabah performs ghusl, and the deceased is left, because this (ghusl for janabah) is obligatory, and that (washing the deceased) is sunnah.'"
