So imagine there's a really important person in charge of a really important place. This place is called the Holy Mosques, which are two big mosques in a faraway country called Saudi Arabia. These mosques are super special to a lot of people around the world who follow a certain religion called Islam.
The person who is in charge of these two important mosques is called the Custodian of the Two Holy Mosques. This is a pretty fancy title, kind of like being a king or a queen. This person has a lot of responsibility because they are in charge of taking care of these two mosques and making sure they are safe and well-looked after.
People in Saudi Arabia really respect this person and consider them to be a very important and powerful leader. They also believe that this person has a special connection to their religion and to God. So the Custodian of the Two Holy Mosques is a pretty big deal!
