Is it permissible to purchase a computer from zakat funds for a charitable organization that distributes them to the needy, knowing that this device was previously bought from household expenses for a person who refused to receive it and pay its price after having requested it?

A wife is not permitted to authorize an organization to disburse Zakat (definition) without her husband's permission. Zakat must not be disbursed in kind, such as an appliance; rather, it must be disbursed in cash and given to the poor. However, if the poor person's interest necessitates purchasing an appliance for him, then it is permissible, as jurists have stipulated the permissibility of giving a poor person from Zakat what he can use to purchase a tool for a craft from which he can earn a living.
