وَ سَأَلَهُ: عَنِ اَلْمَرْأَةِ اَلْمُسْلِمَةِ تَمُوتُ وَ لَيْسَ مَعَهَا اِمْرَأَةٌ مُسْلِمَةٌ وَ لاَ رَجُلٌ مُسْلِمٌ مِنْ ذَوِي قَرَابَتِهَا وَ مَعَهَا نَصْرَانِيَّةٌ وَ رِجَالٌ مُسْلِمُونَ فَقَالَ «تَغْتَسِلُ اَلنَّصْرَانِيَّةُ ثُمَّ تُغَسِّلُهَا.
The Imam was asked about a Muslim woman who dies and is accompanied by no Muslim women or male Muslim relatives, but there is Christian woman and Muslim men present. Imam عليه السلام replied: "The Christian woman should first perform ghusl (ritual washing for herself), and then She should wash the deceased."
