وَعَنْ اِبْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا
أَنَّ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «يُودَى اَلْمُكَاتَبُ بِقَدْرِ مَا عَتَقَ مِنْهُ دِيَةَ اَلْحُرِّ، وَبِقَدْرِ مَا رَقَّ مِنْهُ دِيَةَ اَلْعَبْدِ»
“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-Nasai.
