Which statement preserves the closing homicide/settlement qualification?

Ada and Qada: The Required Act and Its Substitute

• The accidental-case payment is compulsory in intentional killing without a separate settlement agreement
• The perpetrator’s willingness to pay suffices, even when the heirs do not accept settlement
• Settlement requires voluntary payment and the heirs’ choice to accept it instead of Qisas
• The heirs’ wish for payment alone makes the perpetrator’s agreement unnecessary in this example
