Officially anyone who declares that "There is one God and Muhammed is his prophet" is a Muslim. But many Muslims argue that the beliefs of the Ahmedi community mean they cannot be part of the faith. There are about 12 million Ahmedi worldwide and their headquarters, originally in Pakistan, are now in London. Their founder, Mirza Ghulam Ahmad, claimed to be a prophet, although a lesser one than Mohammed, and it is this claim that critics say put his followers outside the fold of Islam.
Joining Ernie to discuss the Ahmedi are Imam Ataul Rashed from the Ahmedi London Mosque, Dr Sahib Bleher founder of the Islamic Party of Britain, and Dr Simon Valentine, author of "Islam and the Ahmaddiya Jama'at.".
