Full Sharh — Al-Adab Al-Mufrad 206
حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ قَالَ: حَدَّثَنِي مَالِكٌ، عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ: كُلُّكُمْ رَاعٍ، وَكُلُّكُمْ مَسْؤولٌ عَنْ رَعِيَّتِهِ، فَالأَمِيرُ الَّذِي عَلَى النَّاسِ رَاعٍ، وَهُوَ مَسْؤولٌ عَنْ رَعِيَّتِهِ، وَالرَّجُلُ رَاعٍ عَلَى أَهْلِ بَيْتِهِ، وَهُوَ مَسْؤُولٌ عَنْ رَعِيَّتِهِ، وَعَبْدُ الرَّجُلِ رَاعٍ عَلَى مَالِ سَيِّدِهِ، وَهُوَ مَسْؤُولٌ عَنْهُ، أَلاَ كُلُّكُمْ رَاعٍ، وَكُلُّكُمْ مَسْؤُولٌ عَنْ رَعِيَّتِهِ.
English Translation
Ibn 'Umar reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "All of you are shepherds and each of you is responsible for his flock. The amir of a people is a shepherd and he is responsible for his flock. A man is the shepherd of the people of his house and he is responsible for his flock. A man's slave is the shepherd of his master's property and he is responsible for it. Each of you is a shepherd and each of you is responsible for his flock."
