Zayd bin Arqam · The Book of Purification and its Sunnah

"I saw the Messenger of Allah performing ablution, washing each part three times, and wiping his head once."

A man asked him: "How much water should I pour over my head when I m sexually impure?" He said: "the messenger of Allah used to pour three handfuls of water over his head." The man said: "My hair is long." He said: "The Messenger of Allah had more hair than you and he was cleaner."

"The Messenger of Allah would not perform ablution after the bath to cleanse himself from sexual impurity."
