To clarify a little bit, it appears that this assignment was part of the class study on world religions, the assignment in question came out of a standard textbook and while it doesn’t have an English translation it does state quite clearly that it is the “Islamic statement of faith”.
Here’s a CNN story, including a picture of the actual assignment.
So to sum up:
-Class specifically includes study of world religions.
-Class uses a standard textbook on the subject.
-Teacher picks an assignment from that same textbook.
-Assignment does say what the phrase is about.
Yes, obviously a case of a rogue teacher stealthily indoctrinating innocent students into an Evil Religion completely outside of the material that they should have been learning.
