Narrated Um Salama:
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.
Whenever Allah's Messenger (ﷺ) completed the prayer with Taslim, the women used to get up immediately and Allah's Messenger (ﷺ) would remain at his place for someone before getting up. (The sub-narrator (Az- Zuhri) said, "We think, and Allah knows better, that he did so, so that the women might leave before men could get in touch with them).
