Narrated Abu Said Al-Khudri:

Some women requested the Prophet 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 ﷺ 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)."

حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ حَدَّثَنِي ابْنُ الأَصْبَهَانِيِّ، قَالَ سَمِعْتُ أَبَا صَالِحٍ، ذَكْوَانَ يُحَدِّثُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ،. قَالَتِ النِّسَاءُ لِلنَّبِيِّ ﷺ 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 ".
