Hadith Regarding Using Water Left by One's Spouse
Narrated by Simak ibn Harb, from Ikrimah, from Ibn Abbas (رضي الله عنه), who reported:"One of the wives of the Prophet (ﷺ) performed ghusl (ritual bath) in a tub. The Prophet (ﷺ) came to use the remaining water for wudu or ghusl. She said, 'O Messenger of Allah! I was in a state of janabah (major impurity).' The Prophet (ﷺ) replied, 'Water does not become impure due to janabah.'"
[Sunan Abu Dawood, also reported by Tirmidhi, who authenticated it]

Key Points Derived from the Hadith
✔ A husband and wife may perform ghusl together (i.e., use the same water source without any restriction).✔ If there is doubt about the purity of water left by either spouse, it is preferable not to use it for ghusl.
✔ Water remains pure by default—a janabah state does not render water impure, meaning that merely using a water container for bathing does not make the remaining water impure (najis).
✔ Modesty between spouses: While performing ghusl together, it is preferable for both husband and wife to cover their private parts with a cloth as an expression of modesty (haya).
