It's Ramadan, Curious George  (English, Board book, Rey H. A.)

It's the first day of Ramadan, and George is celebrating with his friend Kareem and his family. George helps Kareem with his first fast and joins in the evening celebration of tasting treats and enjoying a special meal. Then, George helps make gift baskets to donate to the needy, and watches for the crescent moon with the man in the yellow hat. Finally George joins in the Eid festivities to mark the end of his very first Ramadan.
