Any proof regarding the saying of the salaf 'Eid Mubarak' or 'Taqaballahu minna wa minkum'

Abu Bakr Al-Siddiq Radhiyallahu anhu said: I will not leave anything Allah's Messenger Sallahu alihi wa ssallam did, except that I will also do it; for I fear that if I were to leave any of his commands and ways I would deviate.(Al-Bukhari, Al-Sahih 2:386
