15th century illustration in a copy of a manuscript by Al-Bīrūnī, depicting Muhammad preaching the Qur'ān in Mecca. (Wikipedia) Early in 2008 controversy was created over the website Wikipedia displaying ancient paintings that depicted the Prophet Muhamed. Over 100,000 people signed a petition that would have censored the paintings from being displayed on the grounds that the Ten Commandments forbid engraved images.
