حَدَّثَنَا صَدَقَةُ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، حَدَّثَنَا أَبُو مُوسَى، عَنِ الْحَسَنِ، سَمِعَ أَبَا بَكْرَةَ، سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم عَلَى الْمِنْبَرِ وَالْحَسَنُ إِلَى جَنْبِهِ، يَنْظُرُ إِلَى النَّاسِ مَرَّةً وَإِلَيْهِ مَرَّةً، وَيَقُولُ ‏"‏ ابْنِي هَذَا سَيِّدٌ، وَلَعَلَّ اللَّهَ أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ مِنَ الْمُسْلِمِينَ ‏"‏‏.‏
Translation
Narrated Muhammad

Anas bin Malik said, "The head of Al-Husain was brought to 'Ubaidullah bin Ziyad and was put in a tray, and then Ibn Ziyad started playing with a stick at the nose and mouth of Al-Husain's head and saying something about his handsome features." Anas then said (to him), "Al-Husain resembled the Prophet more than the others did." Anas added, "His (i.e. Al-Husain's) hair was dyed with Wasma (i.e. a kind of plant used as a dye).
