In reply to a handbill issued by the Aryah Samaj on 8 February 1903, the Promised Messiah^(as) had written a book entitled Nasim-e-Da‘wat (An Invitation) on 28 February 1903. This book refuted the abusive insults they had hurled upon the Holy Prophet(sa), and exposed the Aryah practice called Niyog, which allows a married woman to have extramarital relations in order to conceive.

During that very time, the Aryah Samaj were holding their annual convention in Qadian. On 1 March 1903, the last day of the convention, Pandit Ram Bhajdat, the President of the Aryah Parti Nadhi Sabha Punjab, Lahore, made the following comment in his speech, referring to the Promised Messiah^(as) and his recently published book, Nasim-e-Da‘wat: ‘Had he spoken to me about this, I would have explained to him all of the benefits of implementing Niyog.’

On 8 March 1903, the Promised Messiah^(as) wrote another booklet entitled Sanatan Dharm to further expound upon the concept of Niyog. The Promised Messiah^(as) decried the practice as vulgar and contrary to human dignity and nature. He applauds the followers of Sanatan Dharm for their courage in rejecting Niyog and maintaining a
respectful demeanour towards Islam.

The Promised Messiah^(as) also recounts a Hindu prophecy about a Reformer to appear in the Latter Days—which he himself is the fulfilment of—and ends the booklet with three basic principles whereby one can distinguish between a living and dead religion.
