It was narrated that Abu Ja'far said:
"We argued about Ghusl in the presence of jabir in 'Abdullah, 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.'" (JA)
