I really liked this video. I don't even like watching these dawah style youtube channels (I prefer other channels) but some vids in the reality series were really good. It really does shows the reality of how easy it is to fall into sin even if someone is practicing. I've seen this happen many times on online forums to good Muslims and so it's no surprise it happens in real life too. Just like in the story of Barsisa, shaytan can use one good deed to mislead you.
