'Umar b. at-Khattab found a silk garment being sold in the market; he purchased it and brought it to Messenger of Allah ﷺ and said: Messenger of Allah, get it and adorn yourself (by wearing it) on the 'Id (days) and for the delegation. Thereupon, Messenger of Allah ﷺ said: That is the dress of one who has no share (in the Hereafter). 'Umar stayed there so long as Allah wished. Then Messenger of Allah ﷺ sent him a silk cloak. 'Umar came back with that to Messenger of Allah ﷺ and said: Messenger of Allah. you said that it is the dress of one who has no share in the Hereafter, but then you sent it to me. Thereupon, Messenger of Allah ﷺ said: You sell it and meet your need (with its proceeds). (Using translation from Muslim 2068d)
وَجَدَ عُمَرُ بْنُ الْخَطَّابِ حُلَّةً مِنْ إِسْتَبْرَقٍ تُبَاعُ فِي السُّوقِ فَأَخَذَهَا فَأَتَى بِهَا النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ ابْتَعْ هَذِهِ فَتَجَمَّلْ بِهَا لِلْعِيدِ وَلِلْوَفْدِ فَقَالَ النَّبِيُّ ﷺ «إِنَّمَا هَذِهِ لِبَاسُ مَنْ لَا خَلَاقَ لَهُ» فَلَبِثَ عُمَرُ مَا شَاءَ اللهُ أَنْ يَلْبَثَ ثُمَّ أَرْسَلَ إِلَيْهِ النَّبِيُّ ﷺ بِحُلَّةِ دِيبَاجٍ فَأَقْبَلَ بِهَا عُمَرُ حَتَّى أَتَى بِهَا النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ قُلْتَ إِنَّمَا هَذِهِ لِبَاسُ مَنْ لَا خَلَاقَ لَهُ ثُمَّ أَرْسَلْتَ إِلَيَّ بِهَذِهِ الْجُبَّةِ فَقَالَ لَهُ النَّبِيُّ ﷺ «تَبِيعُهَا أَوْ تُصِيبُ بِهَا حَاجَتَكَ»
