‘Umar b. al-Khattab saw a silken suit sold at the gate of the mosque. He said: Messenger of Allah, would that you purchase this suit and wear it on Friday and on the occasion when a delegation (from the outside) comes to you. The Messenger of Allah ﷺ said: One who has no share in the afterlife will put on this (suit). Afterwards suits of similar nature were brought to the Messenger of Allah ﷺ. He gave ‘Umar b. al-Khattab one of these suits. ‘Umar said: Messenger of Allah, you are giving it to me for use while you had told me such-and-such about the suit of ‘Utarid (I.e. sold by ‘Utarid). The Messenger of Allah ﷺ said: I did not give it to you that you should wear it. Hence ‘Umar gave it to his brother who was a disbeliever at Mecca for wearing. (Using translation from Abū Dāʾūd 1076)
أَنَّ عُمَرَ رَأَى حُلَّةً سِيَرَاءَ تُبَاعُ عِنْدَ بَابِ الْمَسْجِدِ فَقَالَ يَا رَسُولَ اللهِ لَوِ اشْتَرَيْتَهَا فَلَبِسْتَهَا يَوْمَ الْجُمُعَةِ وَلِلْوُفُودِ إِذَا قَدِمُوا عَلَيْكَ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّمَا يَلْبَسُ هَذِهِ مَنْ لَا خَلَاقَ لَهُ فِي الْآخِرَةِ ثُمَّ جَاءَتْ رَسُولَ اللهِ ﷺ مِنْهَا حُلَلٌ فَأَعْطَى عُمَرَ مِنْهَا حُلَّةً فَقَالَ عُمَرُ يَا رَسُولَ اللهِ كَسَوْتَنِيهَا وَقَدْقُلْتَ فِيهَا مَا قُلْتَ فَقَالَ رَسُولُ اللهِ ﷺ إِنِّي لَمْ أَكْسُكَهَا لَتَلْبَسَهَا إِنَّمَا كَسَوْتُكَهَا لِتَبِيعَهَا أَوْ لِتَكْسُوَهَا قَالَ فَكَسَاهَا عُمَرُ أَخًا لَهُ مُشْرِكًا مِنْ أُمِّهِ بِمَكَّةَ
