Hadith 532

Narrated Humayd al-Himyari: I met a man who had accompanied the Prophet ﷺ for four years, just as Abu Huraira had. He said: The Messenger of Allah ﷺ forbade a woman from performing ghusl (ritual bath) with the leftover water of a man, or a man from performing ghusl with the leftover water of a woman. Musaddad added: "And both should scoop the water together." [Narrated by Abu Dawood and Al-Nasa'i. Ahmad added at the beginning: "He forbade one of us from combing his hair every day or urinating in a bath." [Narrated by Ibn Majah from Abdullah ibn Sargis] Our scholars said: "This prohibition is for discouragement."
