Sahih Muslim 321 d
'A'isha reported:
I and the Messenger of Allah (ﷺ) took a bath from one vessel which was placed between me and him and he would get ahead of me, so that I would say: Spare (some water for) me, spare (some water for) me; and she said that they had had sexual intercourse.
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ مُعَاذَةَ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَغْتَسِلُ أَنَا وَرَسُولُ اللَّهِ، صلى الله عليه وسلم مِنْ إِنَاءٍ - بَيْنِي وَبَيْنَهُ - وَاحِدٍ فَيُبَادِرُنِي حَتَّى أَقُولَ دَعْ لِي دَعْ لِي ‏.‏ قَالَتْ وَهُمَا جُنُبَانِ ‏.‏
