Is it permissible to invest the money of a deceased person who has no heirs by transferring it to an Arab Islamic country, while retaining the principal for the deceased, taking one-third of the profits, and distributing the remaining two-thirds to the poor and the sick?

If a Muslim dies with no heirs, their wealth reverts to the Muslim treasury (Bayt al-Mal) to be spent on public interests such as mosques, schools, and hospitals. Jurists have differed as to whether it reverts to Bayt al-Mal as fay' (spoils of war/revenue for public good) or as inheritance. Bayt al-Mal is administered by the state and funded from several sources, including the inheritance of those who have no heirs. These funds are spent on the general welfare of Muslims. It is not permissible to invest this money; rather, it must be spent on the interests of Muslims.
