The publish date of Izala Auham is a mystery. It was published in two parts, in this specific video, Mirza Tahir Ahmad writes that it was published in June of 1891, however, all other evidence from Ahmadiyya proves that it was published in September of 1891. Mirza Tahir Ahmad doesn’t reveal his methodology, which is common for Ahmadi mullahs. Nonetheless, I am thinking that Part-1 of Izala Auham was published in June of 1891, and the second Part might have been published in Sept of 1891.
