Virtues of Hanzalah bin Abdullah (may Allah be pleased with him): his martyrdom in a state of janabah and the angels washing him

Ibrahim bin Ishaq narrates from his father, and he from his grandfather, that Hanzalah bin Abi Amir (may Allah be pleased with him) married and spent with his wife the night whose morning was to be the Battle of Uhud. When he had prayed the dawn prayer, Jamilah (his wife) held on to him again, so he went back to her and had relations with her, as a result of which he entered a state of major ritual impurity (janabah). Then he (having no time for the ritual bath) joined the Messenger of Allah (peace and blessings be upon him).

Yahya bin Abbad bin Abdullah narrates from his father, and he from his grandfather, who said: I heard the Messenger of Allah (peace and blessings be upon him) speak at the time of the martyrdom of Hanzalah bin Abi Amir, when he and Abu Sufyan bin al-Harith had confronted each other and Shaddad bin al-Aswad had struck him with a sword and martyred him. The Messenger of Allah (peace and blessings be upon him) said: "The angels are washing your companion, so ask his wife (about the reason)." She told them that when he heard the call to battle, he set out while still in a state of major ritual impurity (janabah), (without having bathed). The Messenger of Allah (peace and blessings be upon him) said: "That is why the angels washed him."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
