Mishkat al-Masabih 3 Purification كتاب الطهارة 144

وَعَنْ عَائِشَةَ قَالَتْ: كُنْتُ أَغْتَسِلُ أَنَا وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ إِنَاءٍ بيني وَبَينه وَاحِد فَيُبَادِرُنِي حَتَّى أَقُولَ دَعْ لِي دَعْ لِي قَالَت وهما جنبان

Mu’adha reported ‘A’isha as saying, “God’s messenger and I used to wash from one vessel which stood between us, and he would get ahead of me, so that I would say, ‘Give me a chance, give me a chance.’ ” She said that they had had sexual intercourse. (Bukhari and Muslim.)
