A lot of questions have been asked regarding why Qadianism (Ahmadiyyat) are not considered muslims, here are the answers :- Full Article

According to the tenet of their faith, the Qadianis (Ahmadis) are required to study, accept, and follow the works, "revelations" (wahi), and writings of Mirza Ghulam Qadiani. In his books, Mirza Ghulam Qadiani makes the claim that he is in direct communication with God and ordains it upon his followers to believe in Islam according to his revelations. We have summarized here some of the differences between Qadianis ( Ahmadis ) and Muslims. It should be obvious that most of the beliefs instructed by Mirza Ghulam Qadiani contradict verses of the Holy Quran -- not to mention hundreds of authentic Hadith and Islamic doctrine.

It is unfortunate that many of the people who have been tricked into accepting Qadianism (Ahmadiyyat) are unaware of this aspect of the Qadiani (Ahmadi) doctrine. Since the rituals of Qadianism resembles that of Islam and much of their ideology is stolen from Islam, many Qadianis are under the impression that they are following an Islamic school of thought. They continue to blindly send their donations to the Qadiani (Ahmadi) leadership thinking they are supporting Islam, when in reality they are helping the enemies of Islam. For the most part, the followers of Qadianism neither have a good grasp of Islam nor have access to the complete writings of Mirza Ghulam Qadiani -- which are mostly written in Urdu -- and are not aware of his blasphemous claims.

The following are some of the difference between Islam and Qadianism ( Ahmadiyyat ):

Qadianism ( Ahmadiyyat ) rejects the concept of absolute Finality of Prophethood in hazrat Muhammad(SAW), as confirmed in Quran, Hadith, Sunnah of the Holy Prophet(SAW), Tradition of Companions, the writings of Saints and Muslim Scholars, and the opinion of the entire Ummah for almost 1500 years.

Qadianism ( Ahmadiyyat ) maintains that Mirza Ghulam Qadiani was a Prophet (nabi and rasul).

Qadianism ( Ahmadiyyat ) is based on the belief that Mirza was the second advent of hazrat Muhammad(SAW).

Qadianism ( Ahmadiyyat ) rejects the concept of completion of the revelations of Allah(SWT) in the Holy Quran.

Qadianism ( Ahmadiyyat ) holds that Mirza Ghulam Qadiani's revelations (Books) were on the same level as all prior revelations (Quran, Bible, Torah).

Qadianism ( Ahmadiyyat ) rejects authentic Hadith based on Mirza's alleged revelations and teaches his personal interpretation of the Holy Quran. Qadiani ( Ahmadiyya ) leadership has forged several unauthentic translations of the Holy Quran to try to confuse and mislead uninformed individuals.

Qadianism ( Ahmadiyyat ) teaches that Jesus(pbuh) was crucified, brought down alive, recovered from his injuries, escaped to Kashmir (India), lived there for 86 more years, died there, is buried there, and won't return.

Qadianism ( Ahmadiyyat ) teaches that Mirza Ghulam Qadiani was also the promised Mehdi.

Qadianism ( Ahmadiyyat ) maintains that Mirza Ghulam Qadiani was also the promised Messiah. The Qadianis ( Ahmadis ) reject the advent of Jesus Christ(pbuh), as the promised Messiah, just before the Day of Judgment.

Qadianism ( Ahmadiyyat ) declares those who do not accept or reject the claims of Mirza to be Kafir. Qadianis have announced all Muslims to be unbelievers and have forbidden their followers from wedding their daughters to Muslims, praying behind Muslims, and offering prayer on their dead - be it a child or an adult Muslim.

Qadianism ( Ahmadiyyat ) has declared Jihad -- specially against the British colonial powers that had occupied India -- Haraam.

Qadianism ( Ahmadiyyat ) requires complete devotion and obedience to the British Government, as an article of faith. Qadianis should be willing to sacrifice their wealth, talent, and soul in the cause of the British. Britain is presently the headquarter of the Qadiani Movement.

Qadianism ( Ahmadiyyat ) holds two cities in India (Qadian) and Pakistan (Rabwah) as holy as Mekkah and Madinah. Qadianis ( Ahmadiyya ) are supposed to perform Hajj by attending their annual congregation, instead of visiting Mekkah.

Qadianism ( Ahmadiyyat ) maintains that Mirza Ghulam Qadiani was superior to all the Prophets(pbut) of Allah(SWT).

Qadianism ( Ahmadiyyat ) refers to the companions of Mirza Ghulam Qadiani as Sahaba and his wives as Mother of the Believers (Ummahatul Muminin).

Qadianism ( Ahmadiyyat ) advances the notion that many verses of the Holy Quran were revealed to Mirza Ghulam Qadiani and that many of the praises of Prophet Muhammad(SAW), mentioned in Quran, were really intended for Mirza Ghulam Qadiani.

Qadianism ( Ahmadiyyat ) claims Mirza's Mosque at Qadian (India) to be Masjid-ul-Aqsa.
