Purdah is a special rule that some people follow in some places. It means that some women decide to cover their faces and bodies when they go outside or are around men who are not part of their family. This is because they want to be respectful and modest.
This covering is called a veil or hijab, and it can be a scarf, a hat, or a piece of fabric that covers their head and part of their face. This is so they are not showing too much of their body or their face to men who are not their family. It is like wearing special clothes to be respectful in a certain place or culture.
People who follow purdah believe it is important to show respect to their family and to God. It is a personal choice, and not everyone follows this rule. Some women choose to wear it all the time, and some only wear it when they go out in public.
It is important to remember that everyone has different beliefs and traditions, and it is important to respect and accept them.
