Sahih al-Bukhari, Hadith 6050 ⓘ

Narrated Ma'rur: I saw Abu Dhar wearing a Burd (garment) and his slave too was wearing a Burd, so I said (to Abu Dhar), "If you take this (Burda of your slave) and wear it (along with yours), you will have a nice suit (costume) and you may give him another garment." Abu Dhar said, "There was a quarrel between me and another man whose mother was a non-Arab and I called her bad names. The man mentioned (complained about) me to the Prophet. The Prophet said, "Did you abuse so-and-so?" I said, "Yes" He said, "Did you call his mother bad names?" I said, "Yes". He said, "You still have the traits of (the Pre-lslamic period of) ignorance." I said. "(Do I still have ignorance) even now in my old age?" He said, "Yes, they (slaves or servants) are your brothers, and Allah has put them under your command. So the one under whose hand Allah has put his brother, should feed him of what he eats, and give him dresses of what he wears, and should not ask him to do a thing beyond his capacity. And if at all he asks him to do a hard task, he should help him therein."

حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، عَنِ الْمَعْرُورِ، عَنْ أَبِي ذَرٍّ، قَالَ رَأَيْتُ عَلَيْهِ بُرْدًا وَعَلَى غُلاَمِهِ بُرْدًا فَقُلْتُ لَوْ أَخَذْتَ هَذَا فَلَبِسْتَهُ كَانَتْ حُلَّةً، وَأَعْطَيْتَهُ ثَوْبًا آخَرَ‏.‏ فَقَالَ كَانَ بَيْنِي وَبَيْنَ رَجُلٍ كَلاَمٌ، وَكَانَتْ أُمُّهُ أَعْجَمِيَّةً، فَنِلْتُ مِنْهَا فَذَكَرَنِي إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ لِي ‏"‏ أَسَابَبْتَ فُلاَنًا ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ أَفَنِلْتَ مِنْ أُمِّهِ ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ إِنَّكَ امْرُؤٌ فِيكَ جَاهِلِيَّةٌ ‏"‏‏.‏ قُلْتُ عَلَى حِينِ سَاعَتِي هَذِهِ مِنْ كِبَرِ السِّنِّ قَالَ ‏"‏ نَعَمْ، هُمْ إِخْوَانُكُمْ، جَعَلَهُمُ اللَّهُ تَحْتَ أَيْدِيكُمْ، فَمَنْ جَعَلَ اللَّهُ أَخَاهُ تَحْتَ يَدِهِ فَلْيُطْعِمْهُ مِمَّا يَأْكُلُ، وَلْيُلْبِسْهُ مِمَّا يَلْبَسُ، وَلاَ يُكَلِّفُهُ مِنَ الْعَمَلِ مَا يَغْلِبُهُ، فَإِنْ كَلَّفَهُ مَا يَغْلِبُهُ فَلْيُعِنْهُ عَلَيْهِ ‏"‏‏.‏
