أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا عَلِيُّ بْنُ الْمُبَارَكِ، عَنْ يَحْيَى، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَضَى رَسُولُ اللَّهِ صلى الله عليه وسلم فِي الْمُكَاتَبِ يُقْتَلُ بِدِيَةِ الْحُرِّ عَلَى قَدْرِ مَا أَدَّى ‏.‏

It was narrated that Ibn 'Abbas said

"The Messenger of Allah ruled that in the case of a Mukatab, the Diyah should be (equivalent) to the Diyah for a free man, proportionate to the amount he had paid off (towards buying his freedom)." (Dar'if)
