Assalamualaikum Are Ahmadis Muslims or not?
Alaikumassalam wa rahmatullah,
The Ahmadiyya rely on the weak hadiths on the Mahdi to claim their religion supersedes traditional Islam (see this previous answer on why I do not believe in the Mahdi). Since they follow the Quran and Sunna they can technically be said to be Muslims, even if their beliefs and practices are not mainstream. I don’t think there is anything to be gained by arguing about whether they are Muslims or not.
