Muwallad is a word that means someone who is of mixed heritage. This means that they have parents of different ethnic or cultural backgrounds. For example, imagine if your mom was from China and your dad was from Mexico. You would be considered a muwallad because you have mixed heritage.
Muwallad was a term that was used a long time ago in places like Spain and other countries where different cultures and religions mixed together. Back then, people used this word to describe someone who had parents who were from different backgrounds.
Today, the word muwallad is not used very much, but some people still use it to describe themselves or their family members who have mixed heritage. It is important to remember that no matter what our background is, we are all humans and we should respect and celebrate each other's differences.
