Jabir b. 'Abdullah reported that Abu Qubafa was led (to the andience of the Holy Prophet) on the day of the Conquest of Mecca and his head and beard were white like hyssop, whereupon Messenger of Allah ﷺ said: Change it with something but avoid black.

وَحَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، عَنِ ابْنِ جُرَيْجٍ، عَنْ أَبِي الزُّبَيْرِ،عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ أُتِيَ بِأَبِي قُحَافَةَ يَوْمَ فَتْحِ مَكَّةَ وَرَأْسُهُ وَلِحْيَتُهُ كَالثَّغَامَةِ بَيَاضًافَقَالَ رَسُولُ اللَّهِ ﷺ " غَيِّرُوا هَذَا بِشَىْءٍ وَاجْتَنِبُوا السَّوَادَ " .
