"The Urdu pamphlet Daî Islâm by Khwaja Hasan Nizami came into his hands. He immediately wrote in answer a pamphlet, the title of which clearly expressed his violent reaction: ‘The Hour of Danger: Hindus, be on your guard! The order has been given to attack and destroy the fortress of your religion in the hidden dead of night!’ (…) The Swami found out that the pamphlet was in fact only the introduction to a larger volume called Fâtamî Dawat-i-Islâm, which had been published as early as 1920, years before the shuddhi of the Malkanas started. In this the Swami saw proof that the Muslim reaction of the day was not merely against the shuddhi and sangathan movements, but rather was part of a sinister plot hatched years earlier. In his pamphlet the Swami went on to show how Nizami in his own introduction referred to his consultations with many Muslim leaders, including the Aga Khan, and how all had agreed that the publication of his work should remain a carefully kept secret within the Muslim community. The single purpose of the pamphlet was to describe all the means, fair and foul, by which Hindus could be induced to become Muslims. (…) In the conclusion of his own booklet, the Swami suggested some ways in which the Muslim threat could be countered. The openness and ethics of his methods stood in strong contrast with Nizami’s tactics.”"
