Intro
As we continue to sift through the books of Ahmadiyya we find inconsistencies and cover-up jobs by the Ahmadiyya mullah team.  In this specific instance, we have found inconsistencies in terms of MGA’s marriage to Nusrat Jehan Begum.

Per “Life of Ahmad” (2008)(1947), current online english edition
On page 133 it states that MGA was married in November of 1884, however, an exact date isn’t given.

Nusrat Jehan had a baby on On April 15th, 1886
Per Ahmadiyya records (dard, page 192), Nusrat Jehan gave birth to Ismat on 4-15-1886.  If we assume that the marriage happened 10 months prior to this, we get July 1885 as the date of marriage.  Ismat died of cholera in 1891, just a few months after MGA’s wildest claims.  

However, in Seerat Nusrat Jehan, they claim that the marriage happened in 1883 and secretly,
Seerat Nusrat Jehan was written by Irfani, who also wrote Hyat e Nasir.  Its the famous Shaikh Yaqub Ali Irfani.  

Date of marriage

The scan of Seerat Nusrat Jehan

Hyat-e-Nasir states that the marriage happened in 1885
Hyat e Nasir and on page 8, says that nikah was performed in 1885. So that is the reason, Irfani who is on the qadiani side, correcting the record by saying that, “mir sahib said that it was 1885 but the correct date is 1883. It is from  official seerat of nusrat jahan writen by Mahmood ahmad Irfani. so it is official.
