Is the questioner not entitled to receive compensation for the damage and the past years from his father's inheritance, in addition to the profit from the sale of the real estate and the two shops?

A clear and explicit agreement must be reached between the son and the father regarding the nature of the money sent, whether it is a loan or an agency, and the ownership of the building or shops must be specified in official documents to avoid future disputes. In the event of a dispute after the father's death, it is recommended that the brothers reconcile through mutual concession, or that the money sent be considered a mudarabah (profit-sharing partnership) whereby the son receives half the value of the properties, and the other half is distributed among the heirs. If they do not agree, the matter should be presented to people of wisdom to estimate a suitable solution.
