Before anyone says that they are kafir or non-Muslim etc, this cannot be true because their shahada is same as any Sunni Muslim. To be a Muslim you have to agree to this shahada: لَا إِلٰهَ إِلَّا الله مُحَمَّدٌ رَسُولُ الله (lā ʾilāha ʾillā l-Lāh, Muḥammadun rasūlu l-Lāh) There is no god but God, Muhammad is the messenger of God. Only difference is that they believe that Mirza Ghulam Ahmad was a Mahdi. I believe that technically the Ahmadiyya Muslims are Sunni Muslim, it is one of the branch of Sunni sect because it inherits majority of its teaching from Sunni school. Bear in mind that technically a certain branch comes under a certain sect according to whatever its teaching is inherited from. e.g. Shia Islam = Alawi, Twelver, Zaydi etc because it inherits its teachings from Shia school Sunni Islam = Ahmadi, Hanafi, Maliki, Wahabi, Salafi etc because it inherits its teachings from Sunni school Please share your intelligence. Here is the Ahmadiyya shahada which is exactly the same as any other Sunni branch: http://www.youtube.com/watch?v=hFiyt-Ijc0Y
