What is the role of an imam during congregational prayer?

In the context of congregational prayer in Islam, the imam serves as the leader of the worshippers.1

During the prayer, the imam stands at the front of the congregation, facing the direction of Mecca. The congregation arranges itself in rows behind him and follows his lead through the various prescribed postures of the prayer, such as standing, genuflection, and prostration.2

For the special congregational prayers held on Friday, the imam also delivers a sermon (khuṭbah). This address typically includes the recitation of verses from the Qurʾān and may cover moral, social, or political topics, often serving as a significant influence on public opinion.2
