So, there's a special building called a mosque where people who follow a religion called Islam go to pray and learn. In a place called Escondido, which is like a little town, there was one of these mosques. But, someone who didn't like Muslims set a fire in the mosque and made it really really damaged. It's not nice or fair to hurt people or damage their important places. The good news is that no one was hurt in the fire, and lots of people in the town came together to support and help fix the mosque.
