Salam alaykum, how do I refuse to tell which country I'm from when people ask me without lying? I say ardhullah or biladullah but some people are quite adamant that I tell them. I don't like to tell where I'm from since it mostly leads to many questions, Qeela wa Qaal and honestly doesn't concern people.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

You do not have to answer everyone who asks you about your country, and there is no harm on you in not answering his question, unless mentioning your country will preserve people's rights, then in this case you are obliged to mention it.

Allah Knows best.
