Intro
Ahmadis will give various excuses in terms of the VERY FIRST statements by any Ahmadi author in terms of the death of Mirza Ghulam Ahmad.  Mir Nasir Nawab and Sheikh Yacoob Ali Irfani (editor of Al-Hakam) (see Dard, page 563 and 564) seem to have collaborated in the mid-1920’s and a biography of Mir Nasir Nawab was written by the famous editor of Al-Hakam. However, Mir Nasir Nawab passed away (1925) before the biography was published. Nonetheless, Hyat-e-Nasir was published from Qadian in 1927.

Ahmadis on social media have doubted the authenticity of this book
Mir Nasir Nawab told the world that MGA thought he had contracted Cholera, the Ahmadiyya jamaat never published a reason of death, however, an independent researcher told the world that MGA died of Cholera (1915).  The Ahmadiyya movement, Lahoris and Qadianis were silent for almost 20 years.  After this book was published, the Indians (muslim, hindu, sikh and etc) began publicizing the fact that MGA thought that he had contracted Cholera and was dying in that state.

Mirza Bashir Ahmad then published Silsila-e-Ahmadiyya, and gave a different story
“On May 25 after offering Maghrib and Isha prayers and taking some food, his father went to bed. At around 11 Pm, he felt the need to use the bathroom. He would often suffer from upset stomach and diarrhea. He had a loose motion and consequently felt weak. He woke up his wife, who immediately got up to look after him and started massaging his feet. Soon after he felt the need to use the privy again. When he returned, he was weak to such an extent that while he was about to lie down on his bed, he wasn’t able to support his own body weight and almost fell on his own bed. Soon, his eldest son and two doctors were also summoned to his bedside and all possible humanly efforts were made to save him. Due to his weakness, Ahmad(As) was also having trouble speaking. The only words that could be heard from him were “O Allah, My Dear Allah” I (Hazrat Mirza Bashir Ahmad(ra) speaking) was standing by him at the time of Fajr prayer. After inquiring whether it was time for prayer he performed Tayammum and tried to offer his prayer in bed. But he fell unconscious. After regaining consciousness, he again inquired about Fajr prayer and offered his prayer while lying down in his bed. He was becoming weaker by the moment and all you could hear were the words “O Allah, My Dear Allah!”At last at about 10:30 AM with his family by his side, he breathed his last and his soul departed from this world towards Allah.””””(((Silsila Ahmadiyya volume 1)))

Mirza Bashir Ahmad lied
He was only 15 at the time.  In fact, he doesn’t even mention that his grandfather was present.
Mirza Bashir Ahmad wasn’t woken-up in the middle of the night, he showed up in the morning.
Obviously, this was a story that was cooked up.  Most likely, MGA died at midnight….after he collapsed and was given an injection (the content of this injection is unknown).

Mirza Tahir Ahmad authenticated Hyat-e-Nasir

Mirza Tahir Ahmad didn’t address the controversial quote

“The night his holiness fell ill, I was sleeping in my room.  When his illness grew severe, they woke me up.  I went over to his holiness and found him in great pain.  He addressed me saying: ‘I have been stricken with cholera.’  After this, he did not utter a single intelligible and coherent word till he died on Monday, after ten O’clock in the morning.”

(Hayat-i-Nasir, P. 14)  Statement of Mir Nasir Nawab in his autobiography compiled by Shaikh Yaqoob Ali Irfani Qadiani.  He was the editor of the Al-Hakam magazine, and thus a very good source of information in terms of Ahmadiyya.

NO children were awoken
All of the children of MGA were not present in the middle of the night when MGA was dying. Noorudin was there, many prominent Lahori-Ahmadis were there.  However, all of them were silent on the topic and remained silent, until they died, as-if they were harboring the truth.

Death by Diarrhea??
I wrote an entire essay on this topic.  Dr. Sutherland seems to be an Ahmadiyya-friend, who was willing to write that MGA died of Diarrhea, which is a lie.

Conclusions
This is another classic case of a cover up by Ahmadiyya leadership.
