Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 22
وَ سَأَلَ عَبْدُ اَلرَّحْمَنِ بْنُ أَبِي نَجْرَانَ أَبَا اَلْحَسَنِ مُوسَى بْنَ جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: عَنْ ثَلاَثَةِ نَفَرٍ كَانُوا فِي سَفَرٍ أَحَدُهُمْ جُنُبٌ وَ اَلثَّانِي مَيِّتٌ وَ اَلثَّالِثُ عَلَى غَيْرِ وُضُوءٍ وَ حَضَرَتِ اَلصَّلاَةُ وَ مَعَهُمْ مِنَ اَلْمَاءِ قَدْرُ مَا يَكْفِي أَحَدَهُمْ مَنْ يَأْخُذُ اَلْمَاءَ وَ كَيْفَ يَصْنَعُونَ فَقَالَ «يَغْتَسِلُ اَلْجُنُبُ وَ يُدْفَنُ اَلْمَيِّتُ بِتَيَمُّمٍ وَ يَتَيَمَّمُ اَلَّذِي هُوَ عَلَى غَيْرِ وُضُوءٍ لِأَنَّ اَلْغُسْلَ مِنَ اَلْجَنَابَةِ فَرِيضَةٌ وَ غُسْلَ اَلْمَيِّتِ سُنَّةٌ وَ اَلتَّيَمُّمَ لِلْآخَرِ جَائِزٌ.
Abdul Rahman ibn Abi Najran asked Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim عليه السلام about three people who were traveling: one was junub (in a state of major ritual impurity), the second was dead, and the third was without wudu (ablution). The time for prayer came, and they had only enough water for one of them. Who should use the water and what should they do? Imam عليه السلام said: 'The one who is junub should perform ghusl (ritual bathing). The deceased should be buried with tayammum, and the one without wudu should perform tayammum because ghusl from janabah is a religious obligation, the washing of the deceased is a recommended practice, and tayammum for the other is permissible.'
