Okay, so na'at is a type of poetry or song that people in some cultures sing or recite to show their love and respect for Prophet Muhammad (peace be upon him). It's like a way of saying thank you to him for all the good things he did and the important lessons he shared. The words are usually in Arabic, which was the language that Prophet Muhammad spoke, and they talk about how great he was and how much he cared for his followers. Some people listen to na'ats to feel closer to Prophet Muhammad or to remind themselves of the things he taught. It's kind of like singing happy birthday to someone you really love and admire, but instead of a birthday, it's to celebrate someone's life and teachings.
