Al-Adab Al-Mufrad, Book 9, Hadith 199 (English) ⓘ
Jabir ibn 'Abdullah said, "The Messenger of Allah, may Allah bless him and grant him peace, advised that slaves be well treated. He said, 'Feed them from what you eat and clothe them from what you wear and do not punish Allah's creation.'"
حَدَّثَنَا عَبْدُ اللهِ بْنُ مَسْلَمَةَ، قَالَ: حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، عَنِ الْفَضْلِ بْنِ 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.
