Hazrat Mirza Ghulam Ahmad (as) undertook the writing of this book as a rejoinder to the filthy and abusive book written by Arya Samaj under the title, Surma Chashm-e-Aryah ki Haqiqat aur fan fraib Ghulam Ahmad ki Kaifiyyat. This attempt by the Arya Samaj was not based on logic or arguments but on provocative and abusive language, not only against Hazrat Mirza Ghulam Ahmad Ahmad (as) but also against the Holy Prophet (sa). Hazrat Ahmad (as) wrote this book in five hours.
The Book
In this book, Hazrat Ahmad (as) refuted the allegations and baseless statements of his enemies. To begin with, Hazrat Ahmad (as) removed the misgiving that he was heavily in debt and reduced to very poor conditions. He pointed out that the allegations that he was not acquainted with the Arya scriptures and was only out to make money by writing such a book against them, could be best refuted by publication of an authorised translation of the Vedas so that the world might judge them for what they were worth. The Vedas might be the oldest books but merely because they are old books they could not be regarded as superior scriptures. Hazrat Mirza Ghulam Ahmad (as) said that the concept of God as presented in the Vedas was most primitive and imperfect. He gave extensive quotations from the Vedas which indicate that the Vedas inculcated the worship of fire, air and water. He also referred to the laws of Manu in which it is laid down that a low caste Hindu is to be put to death if he commits adultery with a high caste girl, but a Brahmun could do so with impunity or by paying a fine. If a Shudra is found listening to the Vedas, his ears are to be stopped with molten lead and wax, and if he should happen to read or memorize the Vedas, his tongue is to be cut off and his heart is to be torn out of the body. Hazrat Ahmad (as) also dealt with some points raised by Pandit Lekh Ram in his book, Takzib Barahin-e-Ahmadiyya, which the Pandit published in reply to Hazrat Ahmad's book, Barahin-e-Ahmadiyya. Hazrat Ahmad (as) exposed the ignorance of Pandit Lekh Ram and pointed out the fallacies in his arguments.
