Sahih Bukhari Volume 3, Book 51, Hadith 2620

حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ دِينَارٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ رَأَى عُمَرُ حُلَّةً عَلَى رَجُلٍ تُبَاعُ فَقَالَ لِلنَّبِيِّ صلى الله عليه وسلم ابْتَعْ هَذِهِ الْحُلَّةَ تَلْبَسْهَا يَوْمَ الْجُمُعَةِ وَإِذَا جَاءَكَ الْوَفْدُ‏.‏ فَقَالَ ‏"‏ إِنَّمَا يَلْبَسُ هَذَا مَنْ لاَ خَلاَقَ لَهُ فِي الآخِرَةِ ‏"‏‏.‏ فَأُتِيَ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْهَا بِحُلَلٍ فَأَرْسَلَ إِلَى عُمَرَ مِنْهَا بِحُلَّةٍ‏.‏ فَقَالَ عُمَرُ كَيْفَ أَلْبَسُهَا وَقَدْ قُلْتَ فِيهَا مَا قُلْتَ قَالَ ‏"‏ إِنِّي لَمْ أَكْسُكَهَا لِتَلْبَسَهَا، تَبِيعُهَا أَوْ تَكْسُوهَا ‏"‏‏.‏ فَأَرْسَلَ بِهَا عُمَرُ إِلَى أَخٍ لَهُ مِنْ أَهْلِ مَكَّةَ قَبْلَ أَنْ يُسْلِمَ‏.‏

Narrated By Ibn 'Umar : Umar saw a silken cloak over a man for sale and requested the Prophet to buy it in order to wear it on Fridays and while meeting delegates. The Prophet said, "This is worn by the one who will have no share in the Hereafter." Later on Allah's Apostle got some silken cloaks similar to that one, and he sent one to 'Umar. 'Umar said to the Prophet "How can I wear it, while you said about it what you said?" The Prophet said, "I have not given it to you to wear, but to sell or to give to someone else." So, 'Umar sent it to his brother at Mecca before he embraced Islam.
