وَ أَخْبَرَنِي اَلشَّيْخُ أَيَّدَهُ اَللَّهُ تَعَالَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ سَعْدِ بْنِ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ يَقْطِينٍ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلنِّسَاءِ أَ عَلَيْهِنَّ غُسْلُ اَلْجُمُعَةِ قَالَ« نَعَمْ».
Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from Sa’d ibn Abdullah, from Ahmad ibn Muhammad ibn Isa, from Ali ibn Yaqtin, who said:
I asked Abu al-Hasan عليه السلام about women: 'Is the ghusl of Friday obligatory for them?' Imam عليه السلام said: 'Yes.'"
