Forty days of solitude

In 1886, certain leaders of the Arya Samaj held discussion and debate with Ghulam Ahmad about the truthfulness of Islam and asked for a sign to prove that Islam was a living religion. In order to dedicate special prayers for this purpose and so as to seek further divine guidance, Ghulam Ahmad traveled to Hoshiarpur upon what he claimed was divine instruction. Here he spent 40 days in seclusion, a practice known as chilla-nashini. He traveled accompanied by 3 other companions to the small 2-storied house of one of his followers and was left alone in a room where his companions would bring him food and leave without speaking to him as he prayed and contemplated. He only left the house on Fridays and used an abandoned mosque for Jumu'ah (Friday prayers). It is during this period that he declared God had given him the glad tidings of an illustrious son.[15][16]
