Intro
Izala Auham is an interesting book.  Ahmadiyya leadership seems to be purposely lying about its publish date.  As we all know, this book came in 2 parts, the first part was published in 1890, before MGA claimed to be Esa (as), and before MGA claimed that Esa (as) was dead.  In fact, Part-1 has some very controversial writings which prove that MGA was a liar and planned all of his claims.  In this particular quote, MGA is claiming that ALL muslims who believe that “abrogation” occurred in Islam are Kafirs.  However, as we all know, in 1891, 99% of the Muslim world believed in the theory of abrogation.  In fact, Sir Syed had denied it in 1880, Noorudin and MGA copied him directly.  It must be noted that the “Quran-only-type-of-Muslims” have existed since the inception of Islam.  However, even those Muslims never declared anyone a Kafir for believing in hadith.  And further, the quran specifically tells Muslims to follow both, the quran and hadith.

The quote
“””Gist of our faith is:  La Ilaha Illallah Muhammadur Rasulullah. (There is no god but Allah, Muhammad is the Messenger of Allah.)

Our belief, which we hold in this life here on earth and to which we will continue to adhere firmly till the time that we pass on to the next world, is that our spiritual leader and master, Muhammad, peace and blessings of Allah be on him, is the Seal of the Prophets and the Best of the Messengers. At his hands religion has been perfected and blessing of Allah has been consummated which lead man to the right path and further on to God Himself. We hold this positive belief with absolute certainty that the Holy Quran is the seal of all Divine books and not an iota can be added to or subtracted from its prescribed teachings, inhibitions, commands and injunctions. There will be no revelation or word from God which may amend or abrogate or change or alter any of the injunctions of the Holy Quran. If anyone subscribes to such views, in our opinion, he ceases to belong to the body of believers and becomes an infidel thereby. (Izala e Auham: Roohani Khaza’in Vol. 3:, p. 170)”””
