مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ سَمَاعَةَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ لَا يَنْبَغِي لِلْمَرْأَةِ أَنْ تَلْبَسَ الْحَرِيرَ الْمَحْضَ وَ هِيَ مُحْرِمَةٌ وَ أَمَّا فِي الْحَرِّ وَ الْبَرْدِ فَلَا بَأْسَ .
12. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from abu Ayyub from Sama‘ah who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘It is not proper for a woman to wear garments of all silk in the state of Ihram, however, in hot or cold weather it is not harmful.’”
