Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْجُعْفِيُّ، حَدَّثَنَا يُونُسُ بْنُ مُحَمَّدٍ، حَدَّثَنَا شَيْبَانُ، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسٌ ـ رضى الله عنه ـ قَالَ أُهْدِيَ لِلنَّبِيِّ صلى الله عليه وسلم جُبَّةُ سُنْدُسٍ، وَكَانَ يَنْهَى عَنِ الْحَرِيرِ، فَعَجِبَ النَّاسُ مِنْهَا، فَقَالَ " وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ، لَمَنَادِيلُ سَعْدِ بْنِ مُعَاذٍ فِي الْجَنَّةِ أَحْسَنُ مِنْ هَذَا "
