Okay kiddo, have you ever seen a hawk before? It's a bird that's really good at flying and hunting.
Now, the "Hawk of Quraish" is a special hawk that is important to a group of people called the Quraish, who lived a long time ago in a place called Arabia. They were a very important group, kind of like a tribe, and they had a symbol that was the hawk.
The story goes that there was a man named Abdullah, who was the father of someone very important named Muhammad. Abdullah had a dream where he saw a hawk that could fly very high and see very far. This hawk had the sun and the moon on its wings, which made it even more special.
When Abdullah told people about his dream, they said it meant that someone in his family would become very important and powerful, kind of like the hawk. And they were right! His son Muhammad went on to become a very important religious leader.
So the "Hawk of Quraish" is really just a symbol for a group of people and a family. It reminds them of their history and their important leaders.
