Is it permissible to give the non-Muslim maid a bonus from Sadqah money?

Answer

If the Sadqah is Naafilah (optional) and it is your own money, then the non-Muslim maid may be given a gift from it. However, if the Sadqah Naafilah is the money of others entrusted to you, then it is necessary to gain their permission before giving it to a non-Muslim.
