Sahih Bukhari, Chapter: Characteristics of Prayer

"The Prophet after finishing the prayer with Taslim used to stay at his place for a while." Ibn Shihab said, "I think (and Allah knows better), that he used to wait for the departure of the women who had prayed." Ibn Shihab wrote that he had heard it from Hind bint Al-Harith Al-Firasiya from Um Salama, the wife of the Prophet (Hind was from the companions of Um Salama) who said, "When the Prophet finished the prayer with Taslim, the women would depart and enter their houses before Allah's Apostle departed."
