Sunan an-Nasa'i · كتاب 45 · كتاب الأيمان والقصاص والدية
a Mukatab was killed at the time of the Messenger of Allah and he commanded that the Diyah be paid (equivalent) to the Diyah for a free man, (proportionate to the amount he had paid off towards buying his freedom)
أَخْبَرَنَا الْقَاسِمُ بْنُ زَكَرِيَّا بْنِ دِينَارٍ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ عَمْرٍو الأَشْعَثِيُّ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ عِكْرِمَةَ، وَعَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ مُكَاتَبًا، قُتِلَ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَمَرَ أَنْ يُودَى مَا أَدَّى دِيَةَ الْحُرِّ وَمَا لاَ دِيَةَ الْمَمْلُوكِ ‏.‏
