Whilst some are busy taking part in Secret Santa, the believers are encouraged to give secret sadaqa.
Abu Hurayra said that the Prophet, may Allah bless him and grant him peace, said, “A man who gives sadaqa, concealing it so that his left hand does not know what his right hand does…” Allah Almighty says, “If you conceal it, and give to the poor, that is better for you.” (2:271)
