In an unprecedented move, an open letter signed by 38 leading Muslim religious scholars and leaders around the world was sent to Pope Benedict XVI on Oct. 12, 2006. The letter, which is the outcome of a joint effort, was signed by top religious authorities such as Shaykh Ali Jumu‘ah (the Grand Mufti of Egypt), Shaykh Abdullah bin Bayyah (former Vice President of Mauritania, and leading religious scholar), and Shaykh Sa‘id Ramadan Al-Buti (from Syria), in addition to the Grand Muftis of Russia, Bosnia, Croatia, Kosovo, Slovenia, Istanbul, Uzbekistan, and Oman, as well as leading figures from the Shi‘a community such as Ayatollah Muhammad Ali Taskhiri of Iran. The letter was also signed by HRH Prince Ghazi bin Muhammad bin Talal of Jordan and by Muslim scholars in the West such as Shaykh Hamza Yusuf from California, Professor Seyyed Hossein Nasr of George Washington University in Washington, D.C., and Professor Tim Winter of the University of Cambridge.
