What's a Imam Khatib?

In Islam, a khatib, khateeb or hatib (Arabic: خطيب‎ khaṭīb) is a person who delivers the sermon (khuṭbah) (literally "narration"), during the Friday prayer and Eid prayers. The khateeb is usually the prayer leader (imam) , but the two roles can be played by different people.

How are imams chosen?

Imams are appointed by the state to work at mosques and they are required to be graduates of an İmam Hatip high school or have a university degree in Theology.

What should one do when the khatib delivers the sermon?

It is commendable for the khatib to be on a pulpit or an elevated place; to salute the congregation when directing himself towards them; to sit down until the adhan is pronounced by the muezzin; and to direct himself straightway to his audience. Finally the khatib should make the sermon short.
