Mirza Qadiani was inspired about his age:
تَرٰی نَسْلاً بَعِیْدًا وَلَنُحْیِیَنَّکَ حَیٰوۃً طَیِّبَۃً۔ ثَمَانِیْنَ حَوْلاً اَوْ قَرِیْبًا مِنْ ذَالِکَ اَوْ تَزِیْدُ عَلَیْہِ سِنِیْنًا۔ وَکَانَ وَعْدُ اللّٰہِ مَفْعُوْلاً۔
Translation: You will see even the distant generation and We will grant you a happy life. Eighty years or thereabouts or a few years more. And Allah’s promise will be fulfilled.
(Tazikra Collection of Revelations and Inspirations, Volume IV, Page 301 by Mirza Qadiani)
Mirza Qadiani said more:
(2) “God the Almighty informed me in clear words that your age will be eighty years or five or six years more or five or six years less.”
(Braheen Ahmadiyya part 5 page 97 above Ruhani Khazain volume 21 page 258 by Mirza Qadiani)
(3) “God gave a promise to Christ that I will save you from the cross and raise you to myself, as Abraham and other holy prophets were raised.” So, contrary to the plans of these people, God gave me a promise that I will give you eighty years or two or three years less or more so that people will not be able to draw the conclusion of lying from the short age.
(Tafah Goldawiya [Appendix] Page 8 of the above Spiritual Treasures Volume 17 Page 44 by Mirza Qadiani)
Mirza Qadiani says in his Divine Inspiration:
(4) “We will grant you a pure and peaceful life. Eighty years or nearly that means twenty years more or less. And you will see a distant generation.”
(Tofah Goldawiya p. 33 above Spiritual Treasures Vol. 17 p. 69 by Mirza Qadiani)
Mirza Qadiani says in response to a question:
(5) “Mashir-e-Ala: Has sir also been informed as to how old you will be?”
Hazrat Aqdas: Yes, about my age, I was told by inspiration that it would be around 80. And now it was known through a vision that I have prayed for 15 more years.
(Appendices, volume III, page 537, 538, modernized by Mirza Qadiani)
Mirza Qadiani was not blessed with Muhammadi Begum’s wife nor was he given extension in age. Only tension was his destiny.
Mirza Qadiani writes in his book:
(6) “Now a person whose life is such that death is present to him every day and there are precedents of the fate of such patients, how can he dare to slander with such a dangerous condition?” And on what health trust does he say that I will be eighty years old? Although medical experiments consider it to be trapped in the clutches of death all the time. People with such diseases die quickly like madduq or end up with cancer.”
(Arbain No. 4 p. 129 above Roohani Khazain Vol. 17 p. 471 by Mirza Qadiani)
(7) “In this place, the issue was also resolved that the Holy Prophet (peace be upon him) should be given respite until the completion of the Qur’an, which was a period of twenty-three years, and be safe from the hostile efforts that were to kill him, and complete his life according to God’s command.” To go along, as for me, is a prediction of eighty years of life until I have accomplished everything.”
(Taifah Al-Induah page 5 of the above Ruhani Khazain Volume 19 page 93 Azmirza Qadiani)
The above-mentioned inspirations and revelations of Mirza Qadiani clearly show that according to Mirza Qadiani, Allah promised him and inspired him that his life would be 80 years or two or three years less or more. On this basis, Mirza Qadiani predicted that his age would be around 80 years. A very simple formula to check whether this prophecy of Mirza Qadiani is true or false is to look at Mirza Qadiani’s date of birth and date of death. No need for a long discussion. There is no dispute among Muslims and Qadianis that Mirza Qadiani died on 26 May 1908. Now it only remains to find out in which year Mirza Qadiani was born? It is decided by Mirza Qadiani’s own writings.
Mirza Qadiani writes in his biography:
(8) “My personal biography is that I was born in 1839 or 1840 during the last period of the Sikhs and I was sixteen or seventeen years old in 1857.”
(Kitab al-Baria page 159 following Spiritual Treasures volume 13 page 177 by Mirza Qadiani)
This is Mirza Qadiani’s own clear writing. There is nothing difficult to interpret anywhere in it. Mirza Qadiani has written clearly and outright that he was born in 1839 or 1840. This is further confirmed by his own other statement that Mirza Qadiani was 34, 35 years old when his father Mirza Ghulam Murtaza died.
Mirza Qadiani writes:
(9) “I was about thirty-four or thirty-five years old when my father died.”
(Kitab al-Baria page 174 following Spiritual Treasures volume 13 page 192 by Mirza Qadiani)
Mirza Ghulam Murtaza died in 1874. This has been acknowledged by Mirza Qadiani on page 116 of his book “Nazul al-Masih”.
(Nazul al-Masih p. 116 above Ruhani Khazain vol. 18 p. 494 by Mirza Qadiani)
Mirza Qadiani was born in 1839 or 1840 and died in 1908.
Readers! Calculate it yourself how old was Mirza Qadiani? If the year of birth is accepted as 1839 then the total age becomes 69 years and if 1840 is accepted then the total age becomes 68 years. Therefore, despite the divine claims, divine revelations and tidings, the age of Mirza Qadiani did not reach 80 years and his prediction proved to be false.
Whereas Mirza Qadiani claims that Allah inspired him:
بَارَکَ اللّٰہُ فِیْ اِلْھَامِکَ وَوَحْیِکَ وَرُؤْیَاکَ۔ (10)
(Translation) May Allah bless you in your inspiration and in your revelation and in your vision.
(Tazikrah Collection of Revelations and Inspirations, Volume IV, Page 569 by Mirza Qadiani)
See another reference in the same series. Mirza Qadiani wrote in his book:
Means, from the day that he will be revealed to himself as an Imam, he will live for forty years. Now it should be clear that this humble person was appointed specially for Da’wa-e-Haq in the fortieth year of his age, and the good news was given that your age is up to eighty years or thereabouts. Ten years have passed perfectly.
(Nishan Asmani Page 14 of the above Spiritual Treasures Volume 4 Page 374 by Mirza Qadiani)
Mirza Qadiani says that he was specially assigned by nature for dawa-haqq and was given the good news through a special inspiration that you will be 80 years old or thereabouts. According to Mirza Qadiani, giving dawat for 40 years is also proved by this inspiration. 10 years have passed since the invitation. 30 years left. Mirza Qadiani wrote this book in 1892. He was 50 years old at that time. As if he had to live for another 30 years for the invitation. In this sense, Mirza Qadiani’s death should have been around 1922, but he died in hell in 1908, only 14 years after his inspired writing, and thus he did not reach the age of 80 years, and this prediction proved to be false.
