Is saying to a kaafir “I wish you well” or “I wish you all the best” on his festival regarded as congratulating him?


I know that congratulating the Christians and Jews for their feats is haram, as it means approving to their baatil (wrong) beliefs. Is it permissible for me to send to whom I know of them messages contain no congratulation? Like sending “ I wish you all good” or “I wish you the best” with an intention of wishing guidance for them?.
