I have question, as I’m pakistani, so here you can say proper campaign has been going on saying “ merry Christmas is equal to agreeing that Hazrat Isa is Son of Allah” Nauzubillah!
Moreover, a bakery has denied to write “merry Christmas “ on cake of christian man.
Is wishing them wrong?
Or writting that” merry Christmas “ on cake wrong?

There’s nothing wrong with wishing Merry Christmas nor does it mean one believes Jesus (as) is god.
