What is the ruling of Islamic law regarding the distribution of the estate of a deceased father, which includes an apartment registered in the name of one of the sons, and shares registered in the names of two daughters and a son, given that the heirs know that the apartment and shares belong to the deceased, and the children were unable to dispose of them or know their value until after his death, and the daughters claim that the shares are compensation for them?

The shares and the apartment must be divided among the heirs according to Islamic law. The two daughters are not entitled to exclusively possess the shares merely because their father registered them in their names, unless they were capable of disposing of them during his lifetime. And if it were presumed to be a gift, it was not taken possession of, so it reverts to the heirs unless they ratify it. However, if it is proven that the gift was complete and they were able to dispose of it during his lifetime, then the shares belong to them. In case of dispute, the matter must be referred to the Sharia court.
