Intro
MGA was a sick man.  He lusted after his niece for almost 20 years, we have found what seems to be his final utterance on this topic.  See my other essay https://ahmadiyyafactcheckblog.wordpress.com/2017/01/10/new-data-on-muhammadi-begum-found-2017/

Summary

When the frustration was at the peak and mirza qadyani could not get married with Mohammadi begum with all his letters to relatives , threats to family and divorces within family ( with her heavenly wife ) as per firm promise of yalash ( god of mirza ) , he said that ” …………..either the Nikkah has been abrogated or has been delayed ”

When MGA died, Nooruddin commented…

 

Now, I would like to remind all the Muslims who have had and still have faith in the Noble Qur’an that since those addressed in it include also their offsprings, successors and those like them, then, can this prophecy not include the daughter, of Ahmad Beg, or the daughter of that daughter ? Does your law of inheritance not apply the regulations regarding daughters to their daughters ? And are the offsprings of the Mirza not his agnates ? I had often told dear Mian Mahmood (Mian Bashiruddin Mahmood, a son of the Mirza and the second head of the Qadiani movement after Hakim Nuruddin. ) that even if the Mirza were to die and this girl did hot enter into his wedlock, my adoration of him would remain unshaken. (Review of Religions, Vol. VII, no. 726, June and July, 1908, p. 279 (cited from Qadiani Mazhab).
