Za'ida bin Qadama al-Thaqifi زائدة بن قدامة الثقفي · The Book of Purification

"This is how the Prophet of Allah (ﷺ) purified himself."

"I saw the Messenger of Allah (ﷺ) wiping over the Khuff."

"I was one who had a lot of prostatic discharge, so I asked the Prophet (ﷺ) and he said: 'If you see Madhi (prostatic fluid) then perform Wudu' and wash your penis, but if you see semen ejaculated, then perform Ghusl.'"

"I asked 'Aishah about how the Messenger of Allah (ﷺ) performed Ghusl from Janabah. She said: 'The Messenger of Allah (ﷺ) used to pour water onto his hands three times, then he would wash his private part, then he would wash his hands, then rinse his mouth and nose, then pour water onto his head three times, then pour water over the rest of his body.'"
