I've seen this vid earlier, subhan'Allah, dont misunderstand me but i think people like him are more blessed, why? for the exact reason the boy himself said. Also most likely have a better chance to enter jannah insha'Allah
I also seen this video before, people like this completely rare. A lot of people start hating God when something bad happens to them, but this boy is a complete inspiration.
You know, just because we see something as "bad" doesn't mean it is. Everything Allah makes possible is good, it will just depend on how one views the situation. At such a young age, this boy can understand this. Amazing. May Allah make it easy for him and keep him close. Ameen.
