Sahih al-Bukhari Book 67, Hadith 148
The Prophet (ﷺ) used to pass by (have sexual relation with) all his wives in one night, and at that time he
had nine wives.
It is the Prophet's tradition that if someone marries a virgin and he has already a matron wife then he should stay for seven days with her (the virgin) and then by turns; and if someone marries a matron and he has already a virgin wife then he should stay with her (the matron) for three days, and then by turns.
Whenever Allah's Messenger (ﷺ) finished his `Asr prayer, he would enter upon his wives and stay with one of them. One day he went to Hafsa and stayed with her longer than usual.
