Kids nowadays learn from parents and friends. Informally, they watch and immitate you behavior.
If since young, you showed them bad example, how can you expect they will grow and become very excellence in everything?
My dear so called parents out there, Islam is simple. But why you are taking easy of it?
Aurah is very simple example.
Covering aurah is an obligation. Cover it from non Mahram. Understand it properly. It doesnt meant cover your aurah when you want to go outside your house or going somewhere.
What it means is, cover your aurah wherever u r if there is non Mahram who can see you. Including in your house. Change your mentality now if you understand this message.
Halal and Haram is not only related to pork and alcohol. In short, it is not only related to you food consumption, but every single thing.
Everything you eat will give impact on your body and soul. It does influence your behavior. It does affect your mental processes. So, please take care of it from the very beggining.
Control, educate, dicipline your children and give motivation from early childhood to ensure they are growing well.
