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.  

أَنَّهُ أُصِيبَ أَنْفُهُ يَوْمَ الْكُلاَبِ فِي الْجَاهِلِيَّةِ فَاتَّخَذَ أَنْفًا مِنْ وَرِقٍ فَأَنْتَنَ عَلَيْهِ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يَتَّخِذَ أَنْفًا مِنْ ذَهَبٍ  

"His nose had been cut off at the battle of Al-Kulab during the Jahiliyyah, so he wore a nose made of silver, but it began to rot on him, so the Prophet [SAW] told him to wear a nose made of gold."  

أُصِيبَ أَنْفُهُ يَوْمَ الْكُلاَبِ فِي الْجَاهِلِيَّةِ قَالَ فَاتَّخَذَ أَنْفًا مِنْ فِضَّةٍ فَأَنْتَنَ عَلَيْهِ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يَتَّخِذَهُ مِنْ ذَهَبٍ
