Ma’rur b. Suwaid said:

I saw Abu Dharr at Rabadhah. He was wearing a thick cloak, and his slave also wore a similar one. He said : the people said: Abu Dharr! (it would be better) if you could take the cloak which your slave wore, and you combined that with, and it would be a pair of garments (hullah) and you would clothe him with another garment. He said: Abu Dharr said : I abused a man whose mother was a non-Arab and I reviled him for his mother. He complained against me to the apostle of allah ﷺ. He said: Abu Dharr! You are a man who has a characteristic of pre-Islamic days. He said: they are your brethren; Allah has given you superiority over them; sell those who do not please you and do not punish Allah’s creatures.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنِ الْمَعْرُورِ بْنِ سُوَيْدٍ، قَالَ رَأَيْتُ أَبَا ذَرٍّ بِالرَّبَذَةِ وَعَلَيْهِ بُرْدٌ غَلِيظٌ وَعَلَى غُلاَمِهِ مِثْلُهُ قَالَ فَقَالَ الْقَوْمُ يَا أَبَا ذَرٍّ لَوْ كُنْتَ أَخَذْتَ الَّذِي عَلَى غُلاَمِكَ فَجَعَلْتَهُ مَعَ هَذَا فَكَانَتْ حُلَّةً وَكَسَوْتَ غُلاَمَكَ ثَوْبًا غَيْرَهُ . قَالَ فَقَالَ أَبُو ذَرٍّ إِنِّي كُنْتُ سَابَبْتُ رَجُلاً وَكَانَتْ أُمُّهُ أَعْجَمِيَّةً فَعَيَّرْتُهُ بِأُمِّهِ فَشَكَانِي إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ " يَا أَبَا ذَرٍّ إِنَّكَ امْرُؤٌ فِيكَ جَاهِلِيَّةٌ " . قَالَ " إِنَّهُمْ إِخْوَانُكُمْ فَضَّلَكُمُ اللَّهُ عَلَيْهِمْ فَمَنْ لَمْ يُلاَئِمْكُمْ فَبِيعُوهُ وَلاَ تُعَذِّبُوا خَلْقَ اللَّهِ " .
