Narrated 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 ﷺ 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 ﷺ 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.

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 ﷺ ابْتَعْ هَذِهِ الْحُلَّةَ تَلْبَسْهَا يَوْمَ الْجُمُعَةِ وَإِذَا جَاءَكَ الْوَفْدُ. فَقَالَ " إِنَّمَا يَلْبَسُ هَذَا مَنْ لاَ خَلاَقَ لَهُ فِي الآخِرَةِ ". فَأُتِيَ رَسُولُ اللَّهِ ﷺ 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.
