His nose was cut off at the battle of Al-Kulab during the Jahiliyyah, so he wore a nose made of silver, but it began to rot, so the Prophet [SAW] told him to wear a nose made of gold. (Using translation from Nasāʾī 5161)
أَنَّهُ أُصِيبَ أَنْفُهُ يَوْمَ الْكُلَابِ فِي الْجَاهِلِيَّةِ فَاتَّخَذَ أنْفًا مِن وَرِقٍ فَأَنْتَنَ عَلَيْه فَأَمَرَهُ النَّبِيُّ ﷺ «أَنْ يَتَّخِذَ أَنْفًا مِن ذَهَبٍ»
