باب لُبْسِ الْحَرِيرِ، وَافْتِرَاشِهِ لِلرِّجَالِ، وَقَدْرِ مَا يَجُوزُ مِنْهُ
Sahih al-Bukhari 5831

Narrated Ibn Abi Laila:

While Hudhaifa was at Al-Madain, he asked for water whereupon the chief of the village brought him water in a silver cup. Hudhaifa threw it at him and said, "I have thrown it only because I have forbidden him to use it, but he does not stop using it. Allah's Messenger (ﷺ) said, 'Gold, silver, silk and Dibaj (a kind of silk) are for them (unbelievers) in this world and for you (Muslims) in the hereafter.'

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنِ ابْنِ أَبِي لَيْلَى، قَالَ كَانَ حُذَيْفَةُ بِالْمَدَايِنِ فَاسْتَسْقَى، فَأَتَاهُ دِهْقَانٌ بِمَاءٍ فِي إِنَاءٍ مِنْ فِضَّةٍ فَرَمَاهُ بِهِ وَقَالَ إِنِّي لَمْ أَرْمِهِ إِلاَّ أَنِّي نَهَيْتُهُ فَلَمْ يَنْتَهِ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ الذَّهَبُ وَالْفِضَّةُ وَالْحَرِيرُ وَالدِّيبَاجُ هِيَ لَهُمْ فِي الدُّنْيَا، وَلَكُمْ فِي الآخِرَةِ ‏"‏‏.‏
