Does the hadith regarding the acceptance of the repentance of the one who killed 99 souls conflict with the obligation for the killer to make himself available to the heirs of the blood?

Question:
May Allah reward you, Your Eminence, father. The questioner asks about the man who killed ninety-nine souls, then repented, so Allah accepted his repentance. Does this conflict with the obligation that the one who kills a soul must make himself available to the heirs of the blood?

Answer:
Imam Ibn al-Qayyim (may Allah have mercy on him) mentioned in al-Jawab al-Kafi and elsewhere that intentional killing involves three rights: a right belonging to Allah, which is dropped by repentance if he repents to Allah; a right belonging to the heirs of the victim, which is dropped either by their pardon, by taking retaliation from him, or by paying them the blood money; and a right belonging to the victim, which remains upon him as the right of the victim until he is resurrected on the Day of Resurrection, and his case is then left to Allah (Glorified and Exalted is He).
