[Machine] The Messenger of Allah ﷺ said: The Mukatab (a slave who is granted the right to buy his freedom) should pay the value of what he has been freed for according to the price of a free person, and what remains due to be paid should be calculated according to the value of a slave.
قَالَ رَسُولُ اللهِ ﷺ الْمُكَاتَبُ يُودَى مَا أَعْتَقَ مِنْهُ بِحِسَابِ الْحُرِّ وَمَا رَقَّ مِنْهُ بِحِسَابِ الْعَبْدِ
