Amman Message
In some places, Muslims implement Islamic law, called sharia in Arabic. The Islamic law exists in a number of variations, called schools of jurisprudence. The Amman Message, which was endorsed in 2005 by prominent Islamic scholars around the world, recognized four Sunni schools (Hanafi, Maliki, Shafi'i, Hanbali), two Shia schools (Ja'fari, Zaidi), the Ibadi school, and the Zahiri school.
