The AfD states that "islam does not belong in Germany", according to its website.
In last year's federal election, AfD supporters have held regular anti-muslim rallies, where they used posters depicting housewives in face veils to get their point across.
Arthur Wagner was in the party's executive committee in the state of Brandenburg but he chose to step down for reasons he claimed to be unrelated.
"Religion is a private matter. We support the constitutional right of religious freedom," Daniel Friese was quoted as saying.
Arthur Wagner was also listed as previously belonging to a group called "Christians in the AfD".
