I am not finding that much information on the Stone-Throwing devils, but I think it could be a reference to the Muslim tradition of "stoning of the devil" in which small rocks are thrown by pilgrims at a wall. People who are racist against Muslims might question who is the devil. That the card is part of the Arabian Nights expansion does not help the cause.

Given the age of the card, it's most likely a reference to the first intifada which was notable for widespread throwing of stones by the Palestinian.
