Mirza Ghulam Ahmad

Re: Mirza Ghulam Ahmad

The reference quoted is Qadiani Madhhab - a biography of Mirza Ghulam Ahmad by Professor Ilyas Burni and Raees-e-Qadian - a biography of Mirza Ghulam Ahmad by Maulana Rafiq Dilawari. However as an ahmadi do you believe these letters to be true or can you present any contrary evidence to suggest otherwise?
