Sahih al-Bukhari 77:58
Narrated `Abdullah bin `Umar:
`Umar saw a silk suit being sold, so he said, "O Allah's Messenger (ﷺ)! Why don't you buy it so that you may wear it when delegates come to you, and also on Fridays?" The Prophet (ﷺ) said, "This is worn only by him who has no share in the Hereafter." Afterwards the Prophet (ﷺ) sent to `Umar a silk suit suitable for wearing. `Umar said to the Prophet, "You have given it to me to wear, yet I have heard you saying about it what you said?" The Prophet (ﷺ) said, "I sent it to you so that you might either sell it or give it to somebody else to wear."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنِي جُوَيْرِيَةُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، أَنَّ عُمَرَ ـ رضى الله عنه ـ رَأَى حُلَّةً سِيَرَاءَ تُبَاعُ فَقَالَ يَا رَسُولَ اللَّهِ لَوِ ابْتَعْتَهَا، تَلْبَسُهَا لِلْوَفْدِ إِذَا أَتَوْكَ وَالْجُمُعَةِ. قَالَ " إِنَّمَا يَلْبَسُ هَذِهِ مَنْ لاَ خَلاَقَ لَهُ ". وَأَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ بَعْدَ ذَلِكَ إِلَى عُمَرَ حُلَّةَ سِيَرَاءَ حَرِيرٍ، كَسَاهَا إِيَّاهُ فَقَالَ عُمَرُ كَسَوْتَنِيهَا وَقَدْ سَمِعْتُكَ تَقُولُ فِيهَا مَا قُلْتَ فَقَالَ " إِنَّمَا بَعَثْتُ إِلَيْكَ لِتَبِيعَهَا أَوْ تَكْسُوَهَا ".
