وَعَنْ اِبْنِ عَبَّاسٍ -رَضِيَ اَللَّهُ عَنْهُمَا- أَنَّ اَلنَّبِيَّ – صلى الله عليه وسلم -قَالَ: { يُودَى اَلْمُكَاتَبُ بِقَدْرِ مَا عَتَقَ مِنْهُ دِيَةَ اَلْحُرِّ, وَبِقَدْرِ مَا رَقَّ مِنْهُ دِيَةَ اَلْعَبْدِ } رَوَاهُ أَحْمَدُ, وَأَبُو دَاوُدَ, وَالنَّسَائِيّ ُ 1 . 1 – صحيح. رواه أحمد (1 / 222- 223 و 226 و 260)، وأبو داود (4581)، والنسائي (8 / 46) واللفظ لأحمد.

Ibn ’Abbas (RAA) narrated that The Messenger of Allah (صلى الله عليه وسلم) said: “The Diyah (Blood money) of a slave who had made an agreement to buy his freedom (Mukatib) and had been killed, is paid at the rate paid for a free man (as a Diyah) as much as he has paid of the amount agreed upon, and at the rate paid for a slave as the remainder is concerned.” Related by Ahmad, Abu Dawud and Au-Nasa’i.
