Attack on the Holy Rock of Islam

In 930 AD, the Qarmatians, a Muslim sect, revolted against the Abbasid Caliphate. This revolt culminated in the sacking of Mecca the capture of the sacred rock of Islam. In addition, the Qarmatians desecrated the Zamzam Well with corpses. The sacred rock was returned to Mecca 22 years later as part of a peace treaty. Imagine if the Crusaders had done this!!
