8ـ حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ سَمَاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ إِسْمَاعِيلَ بْنِ الْفَضْلِ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الْمَرْأَةِ هَلْ تَصْلُحُ لَهَا أَنْ تَلْبَسَ ثَوْباً حَرِيراً وَهِيَ مُحْرِمَةٌ قَالَ لا وَلَهَا أَنْ تَلْبَسَهُ فِي غَيْرِ إِحْرَامِهَا.

8. Humayd ibn Ziyad has narrated from al-Hassan ibn Sama‘ah from more than one person from Aban ibn ‘Uthman from ‘Isma‘il ibn al-Fadl who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a woman if she can use silk clothes in the state of Ihram. He (the Imam) said, ‘No, but she can use them in times other than her being in the state of Ihram.’”
