Hi there, "I am Muslim too" sounds a bit rough - I would probably choose to use "I am a Muslim as well" "I am also Muslim" sounds better than "I am Muslim too".

Both are correct but "I'm a Muslim too" is probably how most native speakers would say it. It's less wordy.

I agree with Elana

" I am also a Muslim" is more formal.

Both are correct grammar, but I would say "I am a Muslim too".
