Respected scholars, As-salamu `alaykum. I am a 16-year-old Christian fromTexas, US, and I was wondering if you could explain what Islam actually is. It is confusing when people here tell me about it. Thank you.

Assalamaliakum. I wanted to ask you "What is bid'ah?" I was told that it is an innovation. I want to know if the actual act is an innovation or the timing of it. for e.g. reading durood shareef loudly after jamah. I believe that reading dur ood is not bid'ah but does reading it in this manner make it bid'ah? Jazakallah
