Definitely, it shouldn't be just religion. They do have to know how to speak their own language. It's something i noticed about myself, when my parents used to speak in urdu or punjabi with me, i wouldnt answer them back in urdu/punjabi always. But now that i have become aware of it and grew up, that importance has also grown for me. It would only make my life difficult not knowing my own language. As i can see with my brother for example, he is always struggling to communicate with desi people in urdu/punjabi. Where as my parents always urged us to not forget it. But Alhamdulillah, ettiquettes are also taught in Islam. We gotta take both of them in each hand, but Islam just a bit higher :)
Well said.
Its very good to learn our language to communicate agar shadi apni qom main hi karni hai deal to unsay hi karna hoga so sub kuch ana chahyay.
Good for you sis you learned language.
