Sahih al-Bukhari 2615, 2616
Narrated Anas:
A Jubba (i.e. cloak) made of thick silken cloth was presented to the Prophet. The Prophet (ﷺ) used to 
forbid people to wear silk. So, the people were pleased to see it. The Prophet (ﷺ) said, "By Him in Whose 
Hands Muhammad's soul is, the handkerchiefs of Sa`d bin Mu`adh in Paradise are better than this." 
Anas added, "The present was sent to the Prophet (ﷺ) by Ukaidir (a Christian) from Dauma."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، 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 ‏"‏‏.‏ وَقَالَ سَعِيدٌ عَنْ قَتَادَةَ، عَنْ أَنَسٍ، إِنَّ أُكَيْدِرَ دُومَةَ أَهْدَى إِلَى النَّبِيِّ صلى الله عليه وسلم‏.‏
