Sunan Ibn Majah, Volume 4, Book 32, Hadith 3591 (DarusSalam) ⓘ

It was narrated from ‘Abdullah bin ‘Umar that ‘Umar bin Khattab saw a silken two piece suit (being offered for sale). He said: “O Messenger of Allah, why don’t you buy this two piece suit (to wear for meeting) the delegations, and on Fridays?” The Messenger of Allah said: “This is only worn by one who has no share in the Hereafter.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، أَخْبَرَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ رَأَى حُلَّةً سِيَرَاءَ مِنْ حَرِيرٍ فَقَالَ يَا رَسُولَ اللَّهِ لَوِ ابْتَعْتَ هَذِهِ الْحُلَّةَ لِلْوَفْدِ وَلِيَوْمِ الْجُمُعَةِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ إِنَّمَا يَلْبَسُ هَذَا مَنْ لاَ خَلاَقَ لَهُ فِي الآخِرَةِ ‏" ‏ ‏.‏
