It was narrated that Abu Ja’far said: “We argued about Ghusl in the presence of Jabir in ‘Abdulláh, and Jabir said: ‘One Sa’ of water is sufficient for Ghusl from Janabah.’ We said: ‘One Sa’ is not enough and neither is two.’ Jabir said: ‘It was sufficient for one who was better than you and had more hair.” (Sahih)
