In some muslim countries, Amir al-Muminin, meaning Commander of the Faithful or Prince of the Faithful, is the religious chief.

Is a title used by Shia muslims to refer to their first Imam, Ali ibn Abi Talib. Sunni Muslims use it to refer to the first four Caliphs, the Four Rightly Guided Caliphs. It has also been adopted by various caliphs of the succeeding Umayyad and Abbasid dynasties, as well as by some contemporary Arab monarchs.

According to the Moroccan constitution king Mohammed VI is also Amir al-Muminin.

Also, the taliban leader Mohammed Omar took the title while he was in control of Afghanistan.
