I live in Canada and in our public schools there's misguidance and sin everywhere. When I was in these public schools students would spread around information about masturbation and suggest it to eachother. There were many Muslims including my Muslim friends who fell into this trap being young and unaware and to this day haven't quit because of their addiction and it has destroyed their spirituality and stopped them from praying salah. Some Muslims have even fell into Zina because of this. I was also victim to this but Alhamduillah I'm free from this filth now. I do however have a younger brother who is approaching the same age where this sort of thing begins to spread around. I'm very worried for him. I don't want him to fall into this sin and end up in the same position as others. How can I protect him from falling into this sin? It is not usual for siblings to talk about this so it is a bit awkward.
