On the authority of Abu Sa'id: that a man asked him about the ritual bath (ghusl) after sexual defilement (janabah), and he said: "Three times." The man said: "But my hair is abundant." He replied: "The Messenger of Allah ﷺ had more hair than you and was purer." (1)

577 — Abu Bakr ibn Abi Shaybah narrated to us, saying: Hafs ibn Ghiyath narrated to us, from Ja'far ibn Muhammad, from his father, from Jabir, who said: I said: "O Messenger of Allah, I am in a cold land, so how should the ritual bath after sexual defilement be performed?" He ﷺ said: "As for me, I pour three handfuls of water over my head." (2)

(1) Sahih by virtue of corroborating evidence, but this chain is weak due to the weakness of 'Atiyyah, who is Ibn Sa'd al-'Awfi. It is found in Ibn Abi Shaybah's "Musannaf" 1/65, and also in his "Musnad," as cited in al-Busiri's "Ittihaf al-Khiyarah" (979).
It is also in "Musnad Ahmad" (11510).
See the preceding narration.
It is corroborated by the hadith of Abu Hurayrah that follows as number (578).
And the hadith of Jabir ibn 'Abdillah is found in al-Bukhari (256) and Muslim (329). It is in the "Musnad" (14188).

(2) Its chain is authentic. Ja'far ibn Muhammad: he is Ibn 'Ali ibn al-Husayn ibn 'Ali ibn Abi Talib, al-Sadiq, and his father is Muhammad ibn 'Ali al-Baqir.
It was also recorded by al-Bukhari (255) and (256), Muslim (329), and al-Nasa'i 1/207 via the path of Abu Ja'far Muhammad ibn 'Ali al-Baqir, from Jabir. Their narration is a report of the Prophet's ﷺ action in that regard.
It is in "Musnad Ahmad" (14188).
It was also recorded by Muslim (328) via the path of Abu Sufyan Talhah ibn Nafi', from Jabir, with the wording of the author.
It is found in Ahmad's "Musnad" (14259).
