Narrated Abu Ja`far:

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.
