Is it permissible for an elderly man to register all his properties in the names of his two daughters, thereby disinheriting his relatives, due to their poor relationship with him and his two daughters?

It is permissible for a father to donate all his possessions to his two daughters, provided there is justice between them. The gift becomes binding if the two daughters take possession of it during the father's lifetime and dispose of it as an owner would. However, if they do not take possession of it before his death, the gift is null and void and is considered a bequest to an heir, unless the rest of the heirs approve it. It is preferable for the father to donate some of his wealth and retain some, to preserve harmony with his relatives and to avoid intentionally disinheriting an heir.
