On April 15, 1907 (Rabiul Awwal 1, 132~ AH), Mirza Ghulam Ahmad Qadiani addressed a public notice to Maulana Sanaullah Amritsari. His published notification included these words:
"If I am a liar and an impostor such as you want to call me in each issue of your periodical then I shall die in your lifetime." (Majmua-e-Ishtiharat Mirza Ghulam Ahmad Qadiani, Vol. 3; p.178).
After that, Mirza invoked Allah's Audience with these words requesting for a Divine Decision:
"If this claim of promised Messiahship is a false imputation from the side of me and if I am in Your Eyes a liar, mischief-monger, imputing false attribute to mine own self as my day/night routine, then, O my dear Master I pray to your Exalted Audience with all possible humility that destroy me in the lifetime of Maulana Sanaullah and let my death make him and his jamaat happy. Now, holding the garment of Your sanctity and Mercy, I supplicate into Your Lofty Audience to bring out true decision between me and Sanaullah and whosoever is really a liar and mischief-monger in Your Eye then carry him off from this world in the very lifetime of the one who is truthful."(Majmua-e-lshtiharat Ghulam Ahmad Qadiani, Vol. 3: p. 549).
Concluding this notification, Mirza Qadiani wrote:
"In the end my request to Maulana Sahib is that he should print all this writing in his periodical and may write underneath whatever he chooses to write. Now decision rests with Allah."
Conforming to the wish of Mirza Qadiani, Maulana Sanaullah printed Mirza's notification, word by word, in his periodical, 'Ahle-Hadith' and added underneath all that he liked to write. Because Mirza Qadiani had entrusted the decision to Allah, having specifically asked for it, all Muslims and Mirzais went into expecting what would come to pass from the unknown realm of the Omniscient Being. Only one year after this, Mirza died. The liar perished on May 26, 1908. Cholera purged Mirza's guts out. The knock-out was sure, certain and precise, one year after his pronouncement in which he had implored Allah for a decision. And Maulana Sanaullah lived on, and on, and on, sound and magnificent, for a long period of forty-one years. It amazed every body. In this way, Mirza Qadiani was once again proved a hoaxer, a knave and a pretender. He was himself bundled off to eternal perdition (Havia) by one stroke of celestial punishment which was enough to silence the babbler.

I think there is no doubt that MGAQ was a liar and Allah has given His verdict too.
Can you see o Qadianis? How can you still beleive in MGAQ?
