Abu Ja'far al-Khutami, 'Umayr bin Yazid عمير بن يزيد أبو جعفر الخطمي · Bathing (Ghusl)

While I and my father were with Jabir bin `Abdullah, some people asked him about taking a bath. He replied, "A Sa` of water is sufficient for you." A man said, "A Sa` is not sufficient for me." Jabir said, "A Sa` was sufficient for one who had more hair than you and was better than you (meaning the Prophet)." And then Jabir (put on) his garment and led the prayer.

Jabir bin `Abdullah said to me, "Your cousin (Hasan bin Muhammad bin Al-Hanafiya) came to me and asked about the bath of Janaba. I replied, 'The Prophet (ﷺ) uses to take three handfuls of water, pour them on his head and then pour more water over his body.' Al-Hasan said to me, 'I am a hairy man.' I replied, 'The Prophet (ﷺ) had more hair than you'. "
