Hazrat Mirza Ghulam Ahmad, the Promised Messiahas published, preached and sent his claim of being the Reformer of the Age far and wide. He sent 8000 copies of registered letters in English to the religious leaders, rulers, scholars, judges and thinkers of Asia, Europe, and America, informing them of his claim in 1885 and inviting them to come and witness the truthfulness of Islam at Qadian. This number exceeded 20,000 in 1891 when he published his book Fath-e-Islam. (The Victory of Islam, p. 13). Hazrat Ahmadas assured that if a sign was not witnessed within a year, a sum of 200 rupees per month, (two thousand four hundred rupees for a year) would be paid as compensation to such an individual. (Majmua Ishtiharat, Vol. 1, pp. 20-22)

Mr Charles Bradlaugh, an English political activist known for his relentless atheism, who founded the National Secular Society in 1866, was among the recipients of this announcement and invitation. At the time of receiving this invitation, he was serving as the liberal MP for Northampton, UK. 

The Cork Constitution of 8 June 1885, reporting on the invitation he received from the Promised Messiahas, wrote:

“Mr Bradlaugh has received a curious invitation, which many people will probably hope he may accept, Mirza Gulam Ahmad who says that he has been commissioned by the Almighty, has sent the junior member for Northampton by registered letter an invitation to visit the Punjab, there to be converted to Islamism, and he offers to guarantee Mr Bradlaugh 200 rupees per month with food and lodging. Mr Bradlaugh has the invitation under his serious consideration.”
