Is it necessary to verify the existence of the association concerned with sponsoring the orphan in the event of giving money to a friend to do so on my behalf?

It is permissible to send money to a trusted friend to deliver it to an orphan girl. This charity is supererogatory, not obligatory, and there is no need to search for an organization; rather, one should purify their intention and seek reward. It is preferable to give sponsorship to needy relatives, as it is both charity and maintaining kinship ties.
