ʿUmar saw a silken cloak over a man for sale and requested the Prophet ﷺ 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 Messenger of Allah ﷺ got some silken cloaks similar to that one, and he sent one to ʿUmar. ʿUmar said to the Prophet ﷺ "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, ʿUmar sent it to his brother at Mecca before he embraced Islam. (Using translation from Bukhārī 2619)
يَا رَسُولَ اللهِ ابْتَعْ هَذِهِ الْحُلَّةَ فَتَلْبَسَهَا يَوْمَ الْجُمُعَةِ وَإِنْ جَاءَ الْوَفْدُ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّمَا يَلْبَسُ هَذِهِ مَنْ لَا خَلَاقَ لَهُ فِي الْآخِرَةِ» فَأُتِيَ رَسُولُ اللهِ ﷺ مِنْهَا بِحُلَلٍ فَأَرْسَلَ إِلَى عُمَرَ بْنِ الْخَطَّابِ مِنْهَا بِحُلَّةٍ فَقَالَ عُمَرُ كَيْفَ أَلْبَسُهَا وَقَدْ قُلْتَ فِيهَا مَا قُلْتَ؟ قَالَ «لَمْ أَكْسُكَهَا لِتَلْبَسَهَا وَلَكِنْ تَبِيعُهَا أَوْ تَكْسُوهَا» فَأَرْسَلَ بِهَا عُمَرُ إِلَى أَخٍ لَهُ مِنْ أَهْلِ مَكَّةَ قَبْلَ أَنْ يُسْلِمَ
