The Prophet ridiculed
This is not a catoon but an illustration from a Dutch-Islamic children's book about the life of the Prophet. This is a good example of how to depict Muhammad if you must make a drawing. Just use a calligraphic symbol.
The actual scene here depict the prophet being ridiculed by the non-believing Quraish people. According to the story, they were throwing goat dung at him when he was praying and laughing at him.
I could not find any reference to the artist that made the illustrations in this book (title: Ik ben een gelukkige druif). if anyone knows who made the drawings, please contact us so we can give her/hin credit)
