[Machine] The Messenger of Allah ﷺ prohibited the exploitation of slaves unless they have a specific skill or a well-known profession. This narration was reported by Ali ibn al-Ja'd from al-Zinji ibn Khalid from Haram ibn Uthman from Abu Atiq from Jabir in a raised hadith.
نَهَى رَسُولُ اللهِ ﷺ عَنْ كَسْبِ الْأَمَةِ إِلَّا أَنْ يَكُونَ لَهَا عَمَلٌ وَاصِبٌ أَوْ كَسْبٌ يُعْرَفُ وَجْهُهُ وَرَوَاهُ عَلِيُّ بْنُ الْجَعْدِ عَنِ الزَّنْجِيِّ بْنِ خَالِدٍ عَنْ حَرَامِ بْنِ عُثْمَانَ عَنْ أَبِي عَتِيقٍ عَنْ جَابِرٍ مَرْفُوعًا
