Sahih Bukhari Volume 4, Book 55, Hadith 2752

حَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ السَّخْتِيَانِيُّ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمٌ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ كُلُّكُمْ رَاعٍ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالإِمَامُ رَاعٍ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالرَّجُلُ رَاعٍ فِي أَهْلِهِ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ، وَالْمَرْأَةُ فِي بَيْتِ زَوْجِهَا رَاعِيَةٌ وَمَسْئُولَةٌ عَنْ رَعِيَّتِهَا، وَالْخَادِمُ فِي مَالِ سَيِّدِهِ رَاعٍ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ ‏"‏‏.‏ قَالَ وَحَسِبْتُ أَنْ قَدْ قَالَ ‏"‏ وَالرَّجُلُ رَاعٍ فِي مَالِ أَبِيهِ ‏"‏‏.‏

Narrated By Ibn Umar : I heard Allah's Apostle saying, "All of you are guardians and responsible for your charges: the Ruler (i.e. Imam) is a guardian and responsible for his subjects; and a man is a guardian of his family and is responsible for his charges; and a lady is a guardian in the house of her husband and is responsible for her charge; and a servant is a guardian of the property of his master and is responsible for his charge." I think he also said, "And a man is a guardian of the property of his father."
