وَ مَا رَوَاهُ أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى عَنِ اَلْحَسَنِ بْنِ عَلِيٍّ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ اَلْحَسَنِ اَلتَّفْلِيسِيِّ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنْ مَيِّتٍ وَ جُنُبٍ اِجْتَمَعَا وَ مَعَهُمَا مَا يَكْفِي أَحَدَهُمَا أَيُّهُمَا يَغْتَسِلُ قَالَ« إِذَا اِجْتَمَعَتْ سُنَّةٌ وَ فَرِيضَةٌ بُدِئَ بِالْفَرْضِ».
The narration of Ahmad ibn Muhammad ibn Isa, from al-Hasan ibn Ali, from Ahmad ibn Muhammad, from al-Hasan al-Taflisi, who said:
I asked Abu al-Hasan عليه السلام about a deceased person and someone in a state of janabah who are together, with only enough water for one of them. Which one of them should use it for ghusl?" Imam عليه السلام replied: "When a sunnah (recommended act) and a fard (obligatory act) coincide, the fard takes precedence."
