How can I calculate my share of the land in exchange for my effort in reclaiming and developing it, taking into account the change in the Iraqi Dinar exchange rate and the increase in the land's value?

The right of the questioner to the land is what he spent on its improvement with the intention of recovering it, which is the aforementioned amount (936). The difference in exchange rates is not taken into account. This amount becomes a debt owed by the father and is not tied to the land itself, unless there was an agreement between them for the father to cede a portion of the land in exchange for what the questioner spent. They can reach an understanding and agreement to compensate the questioner for what he spent, or to include him as a partner in it.
