Regarding the rights of slaves
حَدَّثَنَا أَبُو كَامِلٍ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، عَنِ الأَعْمَشِ، بِإِسْنَادِهِ وَمَعْنَاهُ نَحْوَهُ قَالَ كُنْتُ أَضْرِبُ غُلاَمًا لِي أَسْوَدَ بِالسَّوْطِ وَلَمْ يَذْكُرْ أَمْرَ الْعِتْقِ .
The tradition mentioned above has also been transmitted by al-A’mash in a similar way to same way to the same effect through a different chain of narrators.
