Sahih Bukhari Volume 9, Book 93, Hadith 7140

حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنِي مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ أَلاَ كُلُّكُمْ رَاعٍ، وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ، فَالإِمَامُ الَّذِي عَلَى النَّاسِ رَاعٍ وَهْوَ مَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالرَّجُلُ رَاعٍ عَلَى أَهْلِ بَيْتِهِ وَهْوَ مَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالْمَرْأَةُ رَاعِيَةٌ عَلَى أَهْلِ بَيْتِ زَوْجِهَا وَوَلَدِهِ وَهِيَ مَسْئُولَةٌ عَنْهُمْ، وَعَبْدُ الرَّجُلِ رَاعٍ عَلَى مَالِ سَيِّدِهِ وَهْوَ مَسْئُولٌ عَنْهُ، أَلاَ فَكُلُّكُمْ رَاعٍ وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ ‏"

Narrated By 'Abdullah bin 'Umar : Allah's Apostle said, "Surely! Everyone of you is a guardian and is responsible for his charges: The Imam (ruler) of the people is a guardian and is responsible for his subjects; a man is the guardian of his family (household) and is responsible for his subjects; a woman is the guardian of her husband's home and of his children and is responsible for them; and the slave of a man is a guardian of his master's property and is responsible for it. Surely, everyone of you is a guardian and responsible for his charges."
