حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ أُهْدِيَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم ثَوْبٌ حَرِيرٌ فَجَعَلُوا يَعْجَبُونَ مِنْ لِينِهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَعْجَبُونَ مِنْ هَذَا لَمَنَادِيلُ سَعْدِ بْنِ مُعَاذٍ فِي الْجَنَّةِ أَحْسَنُ مِنْ هَذَا " . قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ . قَالَ وَهَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
