Okay kiddo, qadiyat is an Arabic word that means "issues" or "matters". Qadiyat is often used to talk about important or controversial topics that people are discussing or debating.
For example, imagine there are two kids on the playground who both want to play with the same toy. This would be a qadiya, or an issue, that needs to be resolved. It's similar in the adult world, where qadiyat might include things like political debates, disagreements over laws or policies, or discussions about cultural values and beliefs.
In some countries, there are special courts called qadiyat courts that focus specifically on resolving legal disputes related to family issues, such as divorce or child custody.
So basically, qadiyat is just a fancy word for important topics that people are talking about or trying to solve.
