Okay, so Islam is a religion that many people follow. However, some people who follow Islam believe that men and women should not be together in certain situations. This is called gender segregation.
Let's imagine that there is a big party happening. Some people who follow Islam might say that men and women should sit in different areas at the party. This means that the men would sit in one place and the women would sit in another.
The reason why some people who follow Islam do this is because they believe it is important to protect men and women from temptations that might lead them to do things they shouldn't do. They also believe that it is better for men and women to focus on their own thoughts and actions instead of being distracted by each other.
However, it is important to know that not all people who follow Islam believe in gender segregation. Some people think that men and women should be treated equally and should be able to be together in all situations. It is up to each person to decide what they think is right.
