Is the forgiveness of a Muslim who has been wrongfully harmed by a criminal sufficient, despite his ignorance of his right to the blood money (diyyah) in Islamic law, or must he be informed of this right?

If the damage from an unintentional offense reaches one-third of the blood money (diyyah) or more, the 'Aqilah (the offender's kin group responsible for paying blood money) bears it. If it is less, it is borne by the offender. For the eye and hand, half the blood money is due if their function is lost; if their function is not lost, then a discretionary compensation (hukūmah) is due. The injured party has the right to pardon the blood money due to them. The rightful claimant must be informed of their right so that they may willingly relinquish it, for the Prophet, peace and blessings be upon him, said: "The property of a Muslim person is not lawful [to take] except with his willing consent."
