سنن النسائي

It was narrated from Salim that: His father said: "Umar bin A-Khattab, may Allah be pleased with him, found a Hullah of Istibraq in the market. He took it and brought it to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah (ﷺ), why don't you buy this and adorn yourself with it for the two 'Eids and when (meeting) the delegations?' The Messenger of Allah (ﷺ) said: 'This is the clothing of one who has no share in the Hereafter,' or: 'This is worn by one who has no share in the Hereafter.' Then as much time passed as Allah (SWT) willed, then the Messenger of Allah (ﷺ) sent to Umar a garment made of Dibaj. He brought it to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah, you said that this is the clothing of one who has no share in the Hereafter, then you sent this to me?' The Messenger of Allah (ﷺ) said: 'Sell it and use the money for whatever you need.'"
