Chapter: The woman is a guardian in her husband's house

باب الْمَرْأَةُ رَاعِيَةٌ فِي بَيْتِ زَوْجِهَا

Narrated Ibn `Umar:

The Prophet (ﷺ) said, "All of you are guardians and are responsible for your wards. The ruler is a guardian and the man is a guardian of his family; the lady is a guardian and is responsible for her husband's house and his offspring; and so all of you are guardians and are responsible for your wards."

حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مُوسَى بْنُ عُقْبَةَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ كُلُّكُمْ رَاعٍ، وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالأَمِيرُ رَاعٍ، وَالرَّجُلُ رَاعٍ عَلَى أَهْلِ بَيْتِهِ، وَالْمَرْأَةُ رَاعِيَةٌ عَلَى بَيْتِ زَوْجِهَا وَوَلَدِهِ، فَكُلُّكُمْ رَاعٍ وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ ‏"‏‏.‏
