(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.
حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، قَالَ حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ الزُّهْرِيِّ، عَنْ هِنْدٍ بِنْتِ الْحَارِثِ، عَنْ أُمِّ سَلَمَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا سَلَّمَ قَامَ النِّسَاءُ حِينَ يَقْضِي تَسْلِيمَهُ، وَيَمْكُثُ هُوَ فِي مَقَامِهِ يَسِيرًا قَبْلَ أَنْ يَقُومَ. قَالَ نَرَى ـ وَاللَّهُ أَعْلَمُ ـ أَنَّ ذَلِكَ كَانَ لِكَىْ يَنْصَرِفَ النِّسَاءُ قَبْلَ أَنْ يُدْرِكَهُنَّ أَحَدٌ مِنَ الرِّجَالِ.
