وَ سَأَلَهُ أَبُو بَصِيرٍ: عَنِ اَلْمَرْأَةِ تَمُوتُ مَنْ أَحَقُّ بِالصَّلاَةِ عَلَيْهَا قَالَ «زَوْجُهَا» فَقَالَ لَهُ اَلزَّوْجُ أَحَقُّ مِنَ اَلْأَبِ وَ اَلْوَلَدِ وَ اَلْأَخِ قَالَ «نَعَمْ وَ يُغَسِّلُهَا.
Abu Basir asked Imam عليه السلام about who has the most right to perform the funeral prayer for a woman who has passed away. Imam عليه السلام replied: "Her husband." Abu Basir then asked: "Does the husband have more right than her father, son, or brother?" The Imam said: "Yes, and he may also wash her."
