4ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَبْدِ الْكَرِيمِ بْنِ عَمْرٍو عَنْ أَبِي بَصِيرٍ قَالَ سُئِلَ أَبُو عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الْخَمِيصَةِ سَدَاهَا إِبْرِيسَمٌ وَلَحْمَتُهَا مِنْ غَزْلٍ قَالَ لا بَأْسَ بِأَنْ يُحْرَمَ فِيهَا إِنَّمَا يُكْرَهُ الْخَالِصُ مِنْهُ.
4. A number of our people have narrated from Sahl ibn Ziyad Ahmad ibn Muhammad from ‘Abd al-Karim ibn ‘Amr from abu Basir who has said the following: “Abu ‘Abd Allah (a.s.), was asked about a fabric in which the warp is silk and its weft is of yarn, if it can be used for Ihram. He (the Imam) said, ‘It is not harmful because it is not pure silk.’”
