Basic beliefs of Ahmadiyyah include that Mirza in a prophet after Prophet Muhammad (peace be upon him) which contradicts basic belief to Islam. We belief that Muhammad was the last prophet and messenger and anyone who believes in a new prophet after him has caused a major change in our creed.

 

For that all Muslim scholars do not even consider them true Muslims even if they claim shahada. Islam cannot be divided; you must take it all as one unit.

 

Almighty Allah knows best.
