(Imām Bukhārī narrates): Yahya bin Qaza'ah narrated to us, he said: Ibrahim bin Sa'd narrated to us from al-Zuhri from Hind bint al-Harith from Umm Salamah, may Allāh be pleased with her, she said that
when the Messenger of Allāh ﷺ turned the salam, the women would stand up at the time of his turning the salam, and he would remain standing at his place for a little while before standing up.
Al-Zuhri said: Allāh knows best! Our view is that he remained standing so that the women might pass before the mixing with the men.
