Repentance from Intentional Killing and the Rights Associated with It

Question:
And he does not apply from the mercy of Allah. Then he repented, so Allah accepted his repentance. Does this conflict with the obligation that one who kills a soul must make himself available to the awliya (close friends of Allah) of the crime?

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 awliya (close friends of Allah) of the killed person, which is dropped either by their pardon, or by their taking retaliation from him, or by paying them the blood money; and the right of the killed person. What remains upon him? The right of the killed person remains upon him until he is resurrected on the Day of Resurrection, and his affair is in the hands of Allah (Glorified and Exalted is He).
