Is it permissible to settle a deferred mahr from eight years ago by offering gold ornaments equivalent to or exceeding the value of the cash mahr, knowing that the wife has agreed to either option?

A man is obligated to pay the agreed-upon mahr (dowry), and it is permissible to mutually agree upon increasing or decreasing it, based on the Almighty's saying: "And there is no blame upon you for what you mutually agree to beyond the obligation." If the woman consents to waive the mahr or part of it, there is no sin, based on the Almighty's saying: "But if they give up willingly to you anything of it, consume it in satisfaction and ease."
