حَدَّثَنَا سَهْلُ بْنُ حَمَّادٍ، حَدَّثَنَا هَمَّامٌ، قَالَ: حَدَّثَنِي قَتَادَةُ، قَالَ: حَدَّثَنِي عَمْرُو بْنُ دِينَارٍ: "أَنَّ أَبَاهُ أَعْتَقَ رَقِيقًا لَهُ فِي مَرَضِهِ، ثُمَّ بَدَا لَهُ أَنْ يَرُدَّهُمْ وَيُعْتِقَ غَيْرَهُمْ، قَالَ: فَخَاصَمُونِي إِلَى عَبْدِ الْمَلِكِ بْنِ مَرْوَانَ، فَأَجَازَ عِتْقَ الْآخِرِينَ، وَأَبْطَلَ عِتْقَ الْأَوَّلِينَ".
Amr bin Dinar narrated that his father freed his slave during his illness, then he felt that he should take him back (i.e., not free him) and free other slaves instead. So those slaves disputed with me before Abdul Malik bin Marwan, and Abdul Malik validated the freedom of the latter group and annulled the freedom of the former.
