Narrated Abu Sa`id Al-Khudri:
حَدَّثَنَا آدَمُ ، قَالَ حَدَّثَنَا شُعْبَةُ ، قَالَ حَدَّثَنِي ابْنُ الأَصْبَهَانِيِّ ، قَالَ سَمِعْتُ أَبَا صَالِحٍ، ذَكْوَانَ يُحَدِّثُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ،. قَالَتِ النِّسَاءُ لِلنَّبِيِّ صلى الله عليه وسلم غَلَبَنَا عَلَيْكَ الرِّجَالُ، فَاجْعَلْ لَنَا يَوْمًا مِنْ نَفْسِكَ. فَوَعَدَهُنَّ يَوْمًا لَقِيَهُنَّ فِيهِ، فَوَعَظَهُنَّ وَأَمَرَهُنَّ، فَكَانَ فِيمَا قَالَ لَهُنَّ " مَا مِنْكُنَّ امْرَأَةٌ تُقَدِّمُ ثَلاَثَةً مِنْ وَلَدِهَا إِلاَّ كَانَ لَهَا حِجَابًا مِنَ النَّارِ ". فَقَالَتِ امْرَأَةٌ وَاثْنَيْنِ فَقَالَ " وَاثْنَيْنِ " .
Some women requested the Prophet (ﷺ) to fix a day for them as the men were taking all his time. On that he promised them one day for religious lessons and commandments. Once during such a lesson the Prophet said, "A woman whose three children die will be shielded by them from the Hell fire." On that a woman asked, "If only two die?" He replied, "Even two (will shield her from the Hell-fire).
