Did Hazrat Mirza Sahib Pass Away After Undertaking a Mubahila (Spiritual Duel) with Maulvi Sanaullah of Amritsar?
4)Book by a prominent disciple of the Promised Meissiah, dr. basharat ahmed, (Mujadad-e-Azam vol II, page 1133 - 1169). This book is available from Lahore ishaat-e-islam (Mujaddid-e-Azam (Vol. 2) by Dr. Basharat Ahmad @ aaiil.org) website. Although I am not a lahori ahmadi but this guy has gone in fair amount of detail to discuss this issue. worth reading
So if you are really searching for the truth, go and read above mentioned material.
In short, Maulvi sanaullah never got the courage to do Mubahila as we know it. He alluded the Mubahila duel offer four times. and this is what happened…(extract from ahmadiyya website ref. no. 1)
"So, as far as the mubahala prayer of Hazrat Mirza Sahibas, published on 15th April 1907, is concerned, in view of the condition therein that the liar die during the lifetime of the true, Maulvi Sanaullah Sahib refused to become the second party to it and on the contrary took the position that the liar as against the true is given more time and longer life to continue his evil deeds. Accordingly, until the demise of Hazrat Mirza Sahibas, Maulvi Sanaullah Sahib not only remained firm on this position but emphasized it further in stronger words. In his booklet Moraqqai Qadiani of August 1907, by publishing the following text, he affixed on himself by his own words the permanent seal of being a liar. He wrote:
The Holy Prophet Muhammad, on whom be peace, in spite of being a true prophet, passed away before Maseelma Kazzab. Maseelma in spite of being a liar died after the true person but because he finally died in disappointment and frustration, therefore, there is no doubt in the authenticity of the prayer.
(Moraqqai Qadiani, August 1907)"
“As far as Hazrat Mirza Sahibas is concerned, he did not reject the condition imposed by Maulvi Sanaullah that the true person would die in the lifetime of the liar until he passed away. Moreover, Maulvi Sanaullah Sahib made it very clear that not only will the liar continue to live after the the death of the true person but also eventually he will die a death of disappointment and frustration.”
"Maulvi Abdul Majid Sohdarvi, biographer of Maulvi Sanaullah Sahib, writes in his book Seerati Sanai, published by Maqbool Aam Press, Lahore, that:
The moment he left his house, vagabonds and looters who were waiting for the opportunity swept in and took everything, including all the household items, cash and jewelry. After looting and robbing, they put the house on fire. That was, however, not the end of it; the looters also put on fire and turned to ashes Maulana’s most precious and valuable collection of books which included some very rare publications worth thousands of rupees and which he had brought together after great pains and expense. The loss of these books was no less distressing to Maulana than the loss of his only son. Those books were the most valuable estate of his life and some of them were so rare that it was not only difficult but impossible to replace them.
This violent grief remained with Maulana until his death and, in fact, these two tragic incidents were the major cause of his sudden death. The sudden loss of his only son and the burning of his most precious collection of books, and the affliction of both of these misfortunes over a short while claimed his life."
