I heard Messenger of Allah ﷺ saying, "Everyone of you is a guardian, and responsible for what is in his custody. The ruler is a guardian of his subjects and responsible for them; a husband is a guardian of his family and is responsible for it; a lady is a guardian of her husband's house and is responsible for it, and a servant is a guardian of his master's property and is responsible for it." I heard that from Messenger of Allah ﷺ and I think that the Prophet ﷺ also said, "A man is a guardian of is father's property and is responsible for it, so all of you are guardians and responsible for your wards and things under your care." (Using translation from Bukhārī 2409)
أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ كُلُّ رَاعٍ مَسْئُولٌ عَنْ رَعِيَّتِهِ الْإِمَامُ رَاعٍ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ وَالرَّجُلُ رَاعٍ فِي أَهْلِهِ وَهُوَ مَسْئُولٌ عَنْ رَعِيَّتِهِ وَالْمَرْأَةُ فِي بَيْتِ زَوْجِهَا رَاعِيَةٌ وَهِيَ مَسْئُولَةٌ عَنْ رَعِيَّتِهَا وَالْخَادِمُ رَاعٍ فِي مَالِ سَيِّدِهِ وَمَسْئُولٌ عَنْ رَعِيَّتِهِ وَالرَّجُلُ فِي مَالِ أَبِيهِ رَاعٍ وَهُوَ مَسْئُولٌ عَنْ رَعِيَّتِهِ وَكُلُّكُمْ رَاعٍ وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ
