The book I am about to write is titled Chashma-e-Masihi. There was really no need for me to write about the beliefs of the Christian clergymen, for, in these days, their own renowned scholars in Europe and America have taken this task upon themselves—one which should have actually been performed by us. Nonetheless, they are doing a wonderful service by revealing the truth about Christianity.
I have recently received a letter from an ill-informed Muslim in Bansbareilly, in which he has expressed serious concern about Yanabi-ul-Islam, a book written by a Christian. It is unfortunate that most Muslims, because of their apathy, do not study my books and are completely ignorant of the blessings that God has bestowed upon me. Furthermore, ignorant Mullahs have also created a barrier between us by repeatedly calling me a kafir. This is why Muslims are not aware that the days have passed when the deception and deceit of the Christians could work, and that we are now in the sixth millennium since the birth of Adam—the time when the Divine dispensation (Silsilah) was destined to triumph. This is the last battle3 between light and darkness, in which light shall be victorious and darkness shall be vanquished. Again, it was really not necessary for me to write about the outdated beliefs of the Christian clergy, but I had to do it on the insistence of the above-mentioned gentleman. May God bless this effort and let this book be a source of guidance for the people. Amin.
Remember, we hold Jesus(as) in great esteem, and regard him as a Prophet of God.4 We are also averse to the kinds of objections raised against him that have recently been published by the Jews. My aim is only to show that just as the Jews attack Jesus and his Gospel out of sheer prejudice, in much the same way the Christians attack the Holy Quran and the Holy Prophet(sa). Christians should not have followed the misguided ways of the Jews, but it is a rule that when people are unable to attack a religion on the basis of truth and justice, many of them resort to slanderous attacks. This is also what the author of Yanabi-ul-Islam has done. The love of this world is the cause of all such evil, otherwise Islam is the only heavenly religion which continues to manifest fresh blessings. It is only through the pure fountain of Islam that man is led to the Living God; and the artificial 'God', who lies buried in Srinagar (Mohallah Khanyar), Kashmir, can be of no avail to anyone. I will now turn to the gentleman from Bareilly and commence this book. 
[It is Allah Who guides to the right path].
Mirza Ghulam Ahmad of Qadian
The Promised Messiah
1st March, 1906
1 In the name of Allah, the Gracious, the Merciful. We praise Allah and invoke His blessings upon His noble Messenger. [Publishers]
2 The title Chashma-e-Masihi does not mean 'Fountain of the Messiah(as)', because the Messiah’s teachings, which have been lost to the world, did not teach the prevailing doctrines. These doctrines have been invented by the Christians themselves, and this is why this book has been named 'Fountain of Christianity'. [Author]
3 The word 'battle' must not be taken to mean a battle fought with swords or guns, for God has now forbidden this kind of Jihad. This form of Jihad was destined to be abolished in the time of the Promised Messiah(as), as foretold by the Holy Quran. Sahih Bukhari also contains the Hadith 
[He (the Promised Messiah) shall put an end to war. - Publishers] which refers to the Promised Messiah(as). [Author]
4 Whatever unpleasant things have come forth from my pen regarding Jesus(as) are only by way of counter accusation. I have done no more than to reproduce the words of the Jews. If only the Christian clergymen could be civil and God-fearing and would stop abusing our Holy Prophet(sa), the Muslims would respond with twenty times greater cordiality. [Author]
