Musannaf Ibn Abi Shaybah 700 — How much suffices a person in a state

Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) said: Some people differed about the bath for janabah in the presence of the Prophet (peace and blessings be upon him). One man said: "As for me, I wash my head so much and so much." The Prophet (peace and blessings be upon him) said: "As for me, I pour three handfuls of water over my head."
