Assalmualaikum brothers and sisters, im 18, born and raised in America. Im a Muslim and proud of it, I read Quran and pray 5 times as well. However, my brother does not do these things, he is 2 years younger than me, 16. He is going through some kind of rebellious stage of adolescence, and is now refusing to do prayer. He says "prayer wont help anything". I am very concerned for my brother, how should I approach him in this situation?
