The Repentance of the Intentional Murderer and the Rights of the Victim

Question:
And it was the case that if a believer was killed intentionally, there was a recompense and a settlement with him, either by the sword or by sale. So if one kills a believer intentionally and settles with him by completing the economy or the adornment, do you tell or

Answer:
If he repents, Allah will accept his repentance. Repentance is beneficial even from disbelief and shirk (associating partners with Allah) so what about murder?
Murder is less severe than disbelief and shirk; it falls under the general scope of repentance. Allah accepts his repentance if he repents, but this does not drop the right of the created being. Ibn al-Qayyim (may Allah have mercy on him) mentioned in his book al-Jawab al-Kafi that intentional murder involves three rights: a right belonging to Allah, which is violated by transgressing His inviolable sanctities, meaning He forbade the killing of a Muslim, so this is his killing, and Allah forgives it. This is dropped by repentance; if he repents, Allah accepts his repentance. A right belonging to the awliya (close friends of Allah) of the victim, which is dropped either by qisas (retaliation in kind), or by forgiveness and taking the blood money, or by forgiveness without compensation. And a right belonging to the victim, which remains in the debtor’s account until the Day of Resurrection. Allah (Exalted and Majestic is He) takes charge of the matter. If he repents to Allah, Allah will satisfy the victim with whatever He wills of His bounty and will free this murderer from the sin and from the right of the victim.
