who said:

“I was present with Ibn Ziyād when the head of al-Ḥusayn was brought before him. He began to prod it with a small cane he was holding, so I said, ‘Indeed, of the two of them he most resembled the Prophet ﷺ.’ (1)

It was likewise transmitted by Jarīr ibn Ḥāzim from Muḥammad.

Al-Naḍr ibn Shumayl narrated it from Hishām ibn Ḥassān, from Ḥafṣah bint Sīrīn, who said that Anas told her, and he said, ‘He was poking it in the nose with a stick.’

Ibn ʿUyaynah narrated from ʿUbayd Allah ibn Abī Yazīd, who said:
‘I saw al-Ḥusayn ibn ʿAlī with hair and beard jet-black, save for a few hairs at the front of his beard.’

Ibn Jurayj narrated from ʿUmar ibn ʿAṭāʾ:
‘I saw al-Ḥusayn dyeing his hair with wasmah (2), an indigo-blue dye; the hair of his head and his beard were intensely black.’

Muḥammad ibn ʿAbd Allah ibn Abī Yaʿqūb narrated from Ibn Abī Nuʿm, who said:
‘I was with Ibn ʿUmar when a man asked him about the blood of a mosquito. He said to him, “Where are you from?” The man replied, “From the people of Iraq.” Ibn ʿUmar said, “Look at this fellow! He asks me about the blood of a mosquito, yet they have killed the son of the Messenger of Allah ﷺ. I heard the Messenger of Allah ﷺ say: ‘They two (al-Ḥasan and al-Ḥusayn) are my two basil plants from this worldly life.’” (3)
