What is the ruling of Sharia on building an orphanage from the Zakat funds collected by a certain charitable organization, knowing that all the beneficiaries are poor orphans who live there for a certain time, then leave giving a chance for other orphans to dwell there. In fact, the orphanage is owned by this organization although it hasn`t covered the cost of its construction. In case it was decided that the orphanage should be sold or demolished, its value is Zakatmoney, which goes to the eligible recipients of Zakat or the poor orphans?
