"Some people will dye their hair black like the breasts of pigeons at the end of time, but they will not even smell the fragrance of Paradise." (Using translation from Nasāʾī 5075)  

«قَوْمٌ يَخْضِبُونَ بِهَذَا السَّوَادِ آخِرَ الزَّمَانِ كَحَوَاصِلِ الْحَمَامِ لَا يَرِيحُونَ رَائِحَةَ الْجَنَّةِ»  

Abu Quhafah was brought on the day of the conquest of Mecca with head and beard while like hyssop. The Messenger of Allah ﷺ said: Change this something, but avoid black. (Using translation from Abū Dāʾūd 4204)  

أُتِيَ بِأَبِي قُحَافَةَ يَوْمَ فَتْحِ مَكَّةَ وَرَأْسُهُ وَلِحْيَتُهُ كَالثَّغَامَةِ بَيَاضًا فَقَالَ رَسُولُ اللهِ ﷺ «غَيِّرُوا هَذَا بِشَيْءٍ وَاجْتَنِبُوا السَّوَادَ»  

"Abu Quhafah was brought to the Messenger of Allah [SAW] and his head and beard were white like the Thaghamah. The Prophet [SAW] said: 'Change this, or dye it.'" (Using translation from Nasāʾī 5242)  

أُتِيَ النَّبِيُّ ﷺ بِأَبِي قُحَافَةَ وَرَأْسُهُ وَلِحْيَتُهُ كَأَنَّهُ ثَغَامَةٌ فَقَالَ النَّبِيُّ ﷺ «غَيِّرُوا وَاخْضِبُوا لِحْيَتَهُ»
