Al-Adab Al-Mufrad, Book 9, Hadith 188 (English) ⓘ
Jabir ibn 'Abdullah said, "The Prophet, may Allah bless him and grant him peace, advised that slaves should be well-treated. He said, 'Feed them from what you eat and clothe them from what you wear. Do not punish what Allah has created.'"
حَدَّثَنَا سَعِيدُ بْنُ سُلَيْمَانَ، قَالَ: حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، قَالَ: حَدَّثَنَا الْفَضْلُ بْنُ مُبَشِّرٍ قَالَ: سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللهِ يَقُولُ: كَانَ النَّبِيُّ صلى الله عليه وسلم يُوصِي بِالْمَمْلُوكِينَ خَيْرًا وَيَقُولُ: أَطْعِمُوهُمْ مِمَّا تَأْكُلُونَ، وَأَلْبِسُوهُمْ مِنْ لَبُوسِكُمْ، وَلاَ تُعَذِّبُوا خَلْقَ اللهِ عَزَّ وَجَلَّ.
