The Ruling on Qadyanis and Their Membership
All praise and thanks be to Allah, and may peace and blessings of Allah be upon the Messenger of Allah and his family and Companions and those who follow his guidance. As for what follows:
The Committee of the Fiqh Academy has examined the matter of the Qadyani sect, which appeared in India in the last century (the nineteenth century of the Christian era), and which is also known as the Ahmadiyah movement. The Figh Academy has studied their beliefs which were propagated by the founder of this sect, Mirza Ghulam Ahmad in 1876 C.E. He claimed that he received revelation and that he was the promised Messiah, and that Prophethood was not sealed with our Prophet, Muhammad bin 'Abdullah, the Messenger of Islam (which is the correct belief of the Muslims, according to the Noble Qur'an and the Sunnah). He claimed that he was Divinely inspired and that more than ten thousand verses were revealed to him and that whoever belies him is a disbeliever, that the Muslims are obligated to make Hajj to Qadyan, because it is (so he claimed,) a holy city, like Makkah and Madinah and that it is the city referred to in the Qur'art as Al- Masjid Al-Aqsa. All of this is declared in his book, which was published under the title Baraheen Ahmadiyah and in his "Treatise', which was published under the title At-Tableegh
The Committee of the Academy also examined the sayings and statements of Mirza Bashir Ad-Deen, the son of Ghulam Ahmad Al-Qadyani and his successor, including what was written in his book called Aynat Sadaqat. "Verily, every Muslim who does not take an oath of allegiance to the promised Messiah (i.e. his father, Mirza Ghulam Ahmad), whether he heard of his name or not, is a disbeliever and outside the fold of Islam." (page 35)
He is also quoted in the Qadyani journal, Al-Fadhl as reporting from his father, Ghulam Ahmad himself that he said: "We disagree with the Muslims in everything: Concerning Allah, the Messenger, the Qur'an, prayer, fasting, Hajj, Zakah. Between us and them is a fundamental difference in all of these things."
In the same journal (third volume) it was said: "Verily, Mirza is the Prophet Muhammad." claiming that he was the fulfillment of the Words of the Qur'an, quoting 'Isa:
and giving glad tidings of a Messenger to come after me, whose name shall be Ahmad.
(The Book of Warning of the Caliphate, page 21)
The Committee also examined what is written and published by scholars and reliable Islamic authors about this Qadyani Ahmadiyah sect clarifying that they are completely outside the fold of Islam.
Based upon this, the Parliamentary Territorial Committee which established the northern borders of the State of Pakistan in the year 1974 C.E. by unanimous agreement of its members declared in its report that the Qadyani sect were a non-Muslim minority among the citizens of Pakistan. In the National Assembly of the Pakistan National Council for all Provinces, all of its members also agreed that the Qadyanis are a non-Muslim minority.
In addition to their beliefs, it has been established from the writings of Mirza Ghulam Ahmad himself through the abundant and continuous letters which he wrote to the English Government in India, which display his support and affection for them, including his declaration that Jihad was forbidden and his refutation of the concept of Jihad, in order to inspire loyalty in the hearts of the Muslims towards the English Colonial Government in India. Because (so he claimed,) the concept of Jihad which some of the ignorant Muslims profess, prevents them from expressing loyalty to the English. In this regard, he said, in the appendix to his book Shahadah Al-Qur'an, sixth edition, page 17: "I firmly believe that as my followers increase, the number of those who believe in Jihad will decrease, because the belief that I am the Messiah or the Mahdi necessitates the rejection of Jihad." (See Professor An- Nadawi's thesis published by the Muslim World League, page 25)
Having studied these documents and others like them, including the numerous manuscripts which make clear the beliefs of the Qadyanis, its founder and its establishment and its dangerous aims the destruction of correct Islamic beliefs and the diversion of the Muslims away from it, and towards misguidance, the Fiqh Committee has unanimously determined that the beliefs of the Qadyanis, known also as Ahmadiyah, are un-Islamic and that the pretension of its followers to be Muslims is no more than an attempt to misguide and deceive; and the Committee of the Fiqh Academy declares that it is incumbent upon the Muslims - governments, scholars, writers, thinkers, preachers and others - to oppose this misguided sect and its followers all over the world. And success is from Allah.
