Who are their Imam for sunni?

In Sunni Islam, there is no single Imam analogous to the role in Shia Islam. Instead, Sunni Muslims follow a variety of scholars and leaders known as imams, who interpret Islamic teachings and lead prayers in mosques. Prominent historical figures such as the founders of the four major Sunni schools of thought—Hanafi, Maliki, Shafi'i, and Hanbali—are highly respected, but each community may have its own local leaders. Ultimately, Sunni Islam emphasizes the collective leadership of scholars rather than a singular authoritative figure.
