وَحَدَّثَنِي إِبْرَاهِيمُ بْنُ مُوسَى الرَّازِيُّ، أَخْبَرَنَا شُعَيْبُ بْنُ إِسْحَاقَ الدِّمَشْقِيُّ، عَنِ الأَوْزَاعِيِّ، حَدَّثَنِي شَدَّادٌ أَبُو عَمَّارٍ، حَدَّثَنِي أَبُو أُمَامَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا لَمْ يَلْبَسْهُ فِي الآخِرَةِ " .

He who wore silk in this world would not wear it in the Hereafter.
