CHAPTER: Urinating In Al-Mustaham (The Bathing Area).
Narrated Abdullah ibn Mughaffal: The Messenger of Allah صلی اللہ علیہ وسلم said: No one of you should make water in his bath and then wash himself there (after urination). The version of Ahmad has: Then performs ablution there, for evil thoughts come from it.
Narrated A Man from the Companions: Humayd al-Himyari said: I met a man (Companion of the Prophet) who remained in the company of the Prophet صلی اللہ علیہ وسلم just as Abu Hurairah remained in his company. He then added: The Messenger of Allah صلی اللہ علیہ وسلم forbade that anyone amongst us should comb (his hair) every day or urinate in the place where he takes a bath.
