4ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيِّ بْنِ يَقْطِينٍ عَنْ أَخِيهِ الْحُسَيْنِ بْنِ عَلِيِّ بْنِ يَقْطِينٍ قَالَ سَأَلْتُ أَبَا الْحَسَنِ (عَلَيْهِ السَّلاَم) عَنِ الْخِصْيَانِ وَالْمَرْأَةِ الْكَبِيرَةِ أَ عَلَيْهِمْ طَوَافُ النِّسَاءِ قَالَ نَعَمْ عَلَيْهِمُ الطَّوَافُ كُلِّهِمْ.
4. Ahmad ibn Muhammad has narrated from al-Hassan ibn Ali ibn Yaqtin who has said the following: “I once asked abu al-Hassan (a.s.), about the castrated people and old women if Tawaf al- Nisa’ is obligatory upon them. He (the Imam) said, ‘Yes, it is obligatory on all of them.’”
