ʿUmar saw a silk suit being sold, so he said, "O Messenger of Allah 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 ʿUmar a silk suit suitable for wearing. ʿUmar 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." (Using translation from Bukhārī 5841)
يَا رَسُولَ اللهِ لَوِ ابْتَعْتَ هَذِهِ الْحُلَّةَ فَلَبِسْتَهَا لِلْوَفْدِ وَلِيَوْمِ الْجُمُعَةِ فَقَالَ «إِنَّمَا يَلْبَسُ هَذِهِ مَنْ لَا خَلَاقَ لَهُ فِي الْآخِرَةِ» إِنَّ رَسُولَ اللهِ ﷺ بَعَثَ بَعْدَ ذَلِكَ إِلَى عُمَرَ بِحُلَّةٍ سِيَرَاءَ مِنْ حَرِيرٍ كَسَاهَا إِيَّاهُ فَقَالَ عُمَرُ يَا رَسُولَ اللهِ كَسَوْتَنِيهَا وَقَدْ سَمِعْتُكَ تَقُولُ فِيهَا مَا قُلْتَ فَقَالَ «تَبِيعُهَا أَوْ تَكْسُوهَا»
