That the Prophet ﷺ said: "When the penalty (of blood money) goes to a Mukatab, or an inheritance, then he inherits in accordance with as much as he is freed from it." And the Prophet ﷺ said: "The Mukatab is given the blood-money of a free person in accordance to what he has paid (for his freedom), and that of a slave in accordance to what remains." [He said:] There is something on this from Umm Salamah.
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَصَابَ الْمُكَاتَبُ حَدًّا أَوْ مِيرَاثًا وَرِثَ بِحِسَابِ مَا عَتَقَ مِنْهُ وَقَالَ النَّبِيُّ ﷺ يُؤَدِّي الْمُكَاتَبُ بِحِصَّةِ مَا أَدَّى دِيَةَ حُرٍّ وَمَا بَقِيَ دِيَةَ عَبْدٍ قَالَ وَفِي الْبَابِ عَنْ أُمِّ سَلَمَةَ
