al-Hasan al-Basri الحسن البصري · The Book on Purification

the Prophet prohibited that a man should urinate in his bathing area. And he said: "It will only cause misgivings." There are narrations on This topic from "a man from among the Companions of the Prophet."

the Prophet said: "Indeed there is a Shaitan for Wudu' who is called "AI-Walahan." So beware of having misgivings about water."

"The Prophet performed Wudu and wiped over the Khuff and 'Imamah." Abu Bakr (one of the narrators) said: "And indeed I heard it from Ibn Al Mughirah."
