Arabic (حجر) for interdiction (of a person). It is a legal action preventing a person from disposing of his/her wealth. Once prevented by the court of law, the person is called mahjur alayhi (interdicted person). Hajr can be imposed on a minor or an insane person for the purpose of preserving his/her wealth (in which case it is initiated to the benefit of the interdicted person). It can also be imposed on a bankrupt debtor (muflis) in order to protect the rights of his creditors (hence it is initiated to the benefit of others).

In Arabic, hajr denotes prevention from acting in a specific way. It also means denial of access to something, detention, etc.
