Sahih Muslim 2072
Sahih Muslim · Book 37: The Book of Clothes and Adornment · The Prohibition Of Using Vessels Of Gold And Silver For Men And Women, And Gold Rings And Silk For Men, But They Are Permissible For Women. Permissibility Of Silken Borders On Garments For Men, But It Should Not Be More Than Four Fingers Wide
Anas b. Malik reported that Allah's Messenger (may Peace be upon him) sent a silk gown to 'Umar, whereupon 'Umar said:
وَحَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ ، وَأَبُو كَامِلٍ - وَاللَّفْظُ لأَبِي كَامِلٍ - قَالاَ حَدَّثَنَا أَبُو عَوَانَةَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الأَصَمِّ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى عُمَرَ بِجُبَّةِ سُنْدُسٍ فَقَالَ عُمَرُ بَعَثْتَ بِهَا إِلَىَّ وَقَدْ قُلْتَ فِيهَا مَا قُلْتَ قَالَ " إِنِّي لَمْ أَبْعَثْ بِهَا إِلَيْكَ لِتَلْبَسَهَا وَإِنَّمَا بَعَثْتُ بِهَا إِلَيْكَ لِتَنْتَفِعَ بِثَمَنِهَا " .
You sent it to me whereas you said what you had to, say (i. e. it is forbidden for men). Thereupon he (the Holy Prophet) said: I did not send it to you so that you might wear it, but I sent it to you so that you might derive benefit from its price.
