(رَسُولُ اللهِ ﷺ اغْتَسَلَ غُسْلًا وَاحِدًا بَعْدَ أَنْ جَامَعَ جَمِيعَ أَزْوَاجِهِ)
(The Prophet ﷺ Performed One Ghusl After Being with All His Wives)
Hadith 455
وَعَنْ أَنَسٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يطوف على نِسَائِهِ وَبِغسْلِ وَاحِد. رَوَاهُ مُسلم
Anas said that the Prophet used to have intercourse with his wives, with only a single washing. Muslim transmitted it.
