"Imam Bukhari has made a patriotic appeal to save the nation. We are seeing divisive forces gaining in the country and his appeal will help counter it. We must unite against the communal forces," Prasad told reporters here.
"BJP and RSS should be banned. They always speak communal language and stoke fire against peace and harmony," he said.
The RJD chief recounted the demolition of Babri Masjid and subsequent riots in various states and said he had always spoken against the BJP, RSS combine.
Bukhari had yesterday appealed to the Muslims to support the Congress in the upcoming Lok Sabha elections so communalism in the country could be checked.
The Imam also asked them to vote for RJD in Bihar and Trinamool Congress in West Bengal.
The Congress and the RJD are fighting in alliance in Bihar in the current Lok Sabha polls.
