It was narrated from Jarir from Sulaiman At-Taimi, from Abu 'Uthman A-Nahdi, who said:"We were with 'Utbah bin Farqad when the letter of 'Umar came, saying that the Messenger of Allah [SAW] said: 'No one wears silk except one who has no share of it in the Hereafter, except this much.'" And Abu 'Uthman gestured with the two fingers that are next to the thumb. And I saw the two of them pointing to the borders of the Tayalisah, so that I could see the Tayalisah.
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ سُلَيْمَانَ التَّيْمِيِّ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، قَالَ كُنَّا مَعَ عُتْبَةَ بْنِ فَرْقَدٍ فَجَاءَ كِتَابُ عُمَرَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَلْبَسُ الْحَرِيرَ إِلاَّ مَنْ لَيْسَ لَهُ مِنْهُ شَىْءٌ فِي الآخِرَةِ إِلاَّ هَكَذَا " . وَقَالَ أَبُو عُثْمَانَ بِأُصْبُعَيْهِ اللَّتَيْنِ تَلِيَانِ الإِبْهَامَ فَرَأَيْتُهُمَا أَزْرَارَ الطَّيَالِسَةِ حَتَّى رَأَيْتُ الطَّيَالِسَةَ .
