وَعَنِ ابْنِ عُمَرَ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَلْبَسُ النِّعَالَ السِّبْتِيَّةَ وَيَصْفِرُّ لِحْيَتَهُ بِالْوَرْسِ وَالزَّعْفَرَانِ وَكَانَ ابْنُ عُمَرَ يَفْعَلُ ذَلِك
Ibn Umar said the Prophet (sallallahu alayhi wa sallam) used to wear tanned leather sandals and dye his beard yellow with wars (a plant of yellow colour in the Yemen, like sesame) and saffron. And Ibn Umar used to do that. Nasai transmitted it.
