Does offering prayer, reciting Quran and being nice to people around me complete my deen? Because I don’t have opportunities to grow more than this, I’m totally dependent on my parents. So I cannot contribute any more to improve deen. JazakAllah!
Read the Quran and follow its principles and ideals in your life, that is all you have to do. Islam doesn’t ask you to do more than you are able, we are all required to do what we can with what we have, whether we are young or old, free or in prison.
Part of being Muslim is the seeking of knowledge, therefore if you are able, you should try to read or watch lectures, whether they are about Islamic topics or anything else that may benefit you. You should never sit content with how you are but always aim higher, always trying to become better than you are now.
