Adding the profits made by one of the heirs before distribution to the inheritance

Q 1: A father died, leaving behind money and sons, but the elder son did not distribute the money among his brothers and sisters, as he invested it in trade. After one year, he made a huge profit from the estate money, and wanted to distribute the money among his brothers. Should he distribute the money of the original estate, or all the money including the profit he earned after the father's death?

A: He has to distribute the inheritance along with the profit among the heirs. If they differed with regard to anything, they can refer the case to a legal court. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
