The muezzin (of the Turkish : muezzin, itself of the Arab driven-aḏḏin rear RTL مؤذّن, that which makes the call ) is the member of the Mosquée charged to launch the call to the prayer (Adhan), at least five times per day, often since the top of one of the Minaret S of the aforesaid the mosque. This call by the voice has seems it be selected to dissociate Jewish call, by a horn, and Christian call, by a bell and also because it is the means most natural to call.

The muezzin is selected for his voice and his personality. In certain mosques, it places in turn vis-a-vis each Point cardinal when it calls with the prayer; during the prayer, it is placed sometimes on a particular platform, called in Turkish muezzin mahfili , opposed to the Minbar and it answers the sermons of the Imam.

The most famous muezzin is Bilal, first nobody to achieve this function with Médine, of the time of Mohammad, in the first Moslem mosque rested by the prophet and his companions of the Hégire.

The muezzin (that which makes the call to the prayer):

• should not require wages
• should not be in a state of large nor of small impurity
• must be upright in direction of the Ka' Ba (which is with Mecque)
• must turn its body from right to left (to be heard in all the directions)
• must stop the ears with the index or the minor (in order not to be disturbed)
• to raise the voice to be of course
• to speak posément to be included/understood well.

More and more, of the calls recorded and diffused by loudspeakers act as muezzin in the Moslem countries.
