True Muslims universally reject Mirza Ghulam Ahmad Qadiani because his claim to prophethood violates the fundamental Islamic belief that Hazrat Muhammad (PBUH) is the absolute final Messenger of Allah. This rejection is a matter of protecting the sanctity of Khatm-e-Nabuwwat, as any claim following the Seal of the Prophets is considered a profound deception and a departure from the fold of Islam. To understand the complete theological evidence and scholarly refutations regarding this issue, you should visit Emaan-e-Kamil.
