"The Messenger of Allah ruled that the Diyah for a Mukatab who is killed should be (equivalent) to the Diyah for a free mand, proportionate to the amount be had paid off (toward buying his freedom)." (Using translation from Nasāʾī 4808)
«قَضَى رَسُولُ اللهِ ﷺ فِي الْمُكَاتَبِ يُقْتَلُ بِدِيَةِ الْحُرِّ عَلَى قَدْرِ مَا أَدَّى»
"The Messenger of Allah ruled that the Diyah for a Mukatab who is killed should be (equivalent) to the Diyah for a free mand, proportionate to the amount be had paid off (toward buying his freedom)."
قَضَى رَسُولُ اللَّهِ ﷺ فِي الْمُكَاتَبِ يُقْتَلُ بِدِيَةِ الْحُرِّ عَلَى قَدْرِ مَا أَدَّى
"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)
قَضَى رَسُولُ اللَّهِ ﷺ فِي الْمُكَاتَبِ يُودَى بِقَدْرِ مَا أَدَّى مِنْ مُكَاتَبَتِهِ دِيَةَ الْحُرِّ وَمَا بَقِيَ دِيَةَ الْعَبْدِ
The Messenger of Allah ﷺ gave judgment about the slave who had made an agreement to purchase his freedom (mukatab) and he had been killed that blood-wit is paid for him at the rate paid for a free man so far as he has paid the purchase money, and at the rate paid for a slave as the remainder is concerned. (Using translation from Abū Dāʾūd 4581)
قَضَى رَسُولُ اللهِ ﷺ فِي الْمُكَاتِبِ يُقْتَلُ يُودَى لِمَا أَدَّى مِنْ مُكَاتَبَتِهِ دِيَةَ الْحُرِّ وَمَا بَقِيَ دِيَةَ الْعَبْدِ
