مَا أَخْبَرَنِي[ أَخْبَرَنِي خ ل] بِهِ اَلشَّيْخُ أَيَّدَهُ اَللَّهُ تَعَالَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ سَعْدِ بْنِ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ اَلْحَسَنِ بْنِ عَلِيِّ بْنِ يَقْطِينٍ عَنْ أَخِيهِ اَلْحُسَيْنِ عَنْ عَلِيِّ بْنِ يَقْطِينٍ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْغُسْلِ فِي اَلْجُمُعَةِ وَ اَلْأَضْحَى وَ اَلْفِطْرِ قَالَ« سُنَّةٌ وَ لَيْسَ بِفَرِيضَةٍ».
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 al-Hasan ibn Ali ibn Yaqtin, from his brother al-Husayn, from Ali ibn Yaqtin, who said:
I asked Abu al-Hasan عليه السلام about the ghusl on Friday, Eid al-Adha, and Eid al-Fitr. Imam عليه السلام said: 'It is a sunnah, not an obligation.'"
