Ibn ‘Umar used to make his beard yellow with a yellow dye so that his clothes were full of it. He was asked why he used the yellow dye and replied, "I saw God's messenger using it as a dye, and he liked nothing better than it. He used to dye all his clothes with it, even his turban.” Abu Dawud and Nasa’i transmitted it.

وَعَنِ ابْنِ عُمَرَ أَنَّهُ كَانَ يَصْفِّرُ لِحْيَتَهُ بِالصُّفْرَةِ حَتَّى تَمْتَلِئَ ثِيَابُهُ مِنَ الصُّفْرَةِ فَقِيلَ لَهُ: لِمَ تُصْبِغُ بِالصُّفْرَةِ؟ قَالَ: أَنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَصْبُغُ بِهَا وَلَمْ يَكُنْ شَيْءٌ أَحَبَّ إِلَيْهِ مِنْهَا وَقد كَانَ يصْبغ ثِيَابَهُ كُلَّهَا حَتَّى عِمَامَتَهُ. رَوَاهُ أَبُو دَاوُدَ وَالنَّسَائِيّ
