If he knew that his parents would be angry when he told the truth about his big win and received the money, it would be better for him not to say anything about it. Better to save the money for a while and act like nothing happened not to arouse any suspicion from his parents. Or he could secretly invest the money into something more beneficial to him. But there was also another option he could make, which was to tell about his winning honestly.
First of all, what he did was wrong because he didn't follow the order of his parent's but now that he already committed the mistake, I think it will now be easy for him to commit another mistake which is to lie, just in case his parents find out about the money. Im sure there must be other profitable activity that is allowed in his country like investing or trading. He can just say that he got the money from those sources. There might still be people who can feel guilty right after making one mistake and they will confess it right away. They think this will lessen the punishment that they will be getting.
His parents loves him and that's why. His will to take an action should not be cause he is afraid of them he must think about god/Allah first. If he don't care about the creator then fuck his parents no need to worry about them.
Our parents are important because without them, we won't exist but without god there's also no people that will exist. There's even a saying that "god must come first". Maybe it's fine to dis-obey our parent's as long as what they are telling to us is not the same as what is written in the bible.
I think something, we are sinners by nature, but here in the case it was a child who did it, and a child generally does not have a mind like that of an adult, yes I know he disobeyed, but tell me something, what Sometimes a child does not disobey his parents (I sometimes did when I was a child) that is why it is not worth playing, secondly I know that without them our parents would have no life and I agree that God is first above all things, in fact the first commandment is that of loving God above all things, so from there we must also ask ourselves, if the child did that, it is because it was allowed to do so.
Now the case of the parents, that a son tells me that he earned a lot of money, but that he earned it because he disobeyed me, well I hug him the same and even with more joy, please how are you going to tell him that not money? He is also a child who did it, I know that the fact is bad, but I think that a person is not that he is comfortable, he is still happy with the end, but I think he can achieve happiness faster or in at least 90% because since money helps people to be happy, that is really what I need the most to be a very happy man, sometimes religions are very radical and make people become or become something they are not , and God does not like that, and the children belong to God, so I think that this is more than forgiven, now those who must ask for forgiveness in this case, without a doubt, God is the father of that child.
There are some things that happen where I am with some religions, where they ask people to give 10% of what they earn, and that seems so incredible to me, because they take advantage of the things of God the Heavenly Father to make money, and that is something that does not reach God, what reaches God are good deeds, or giving money to someone who really needs it, not for a Church, in fact in the Bible it says something like that, it does not reach God to the one who gives more money to a Church but other works that actually have spiritual weight.
