Allah has Cleary Stated in the Qur’an, that a false claim would not prosper:
وَلَوْ تَقَوَّلَ عَلَيْنَا بَعْضَ الْأَقَاوِيلِ {45} لَأَخَذْنَا مِنْهُ بِالْيَمِينِ {46} ثُمَّ لَقَطَعْنَا مِنْهُ الْوَتِينَ {47} فَمَا مِنْكُمْ مِنْ أَحَدٍ عَنْهُ حَاجِزِينَ {48}
And if he had forged and attributed any sayings to Us,We would surely have seized him by the right hand,And then surely We would have severed his life-arteryAnd not one of you could have held Us off from him. (Chapter 69 Verse 45-48)
These verses are beautiful proofs which show the truthfulness of Ahmadas as well. It is clear that one who lies about revelation from Allah, is bound to be destroyed. this was revealed to the Prophet Muhammadsaw and he live for 23 years after his first revelation, which tells us that a sign of ones truthfulness, is living for 23 years after his first revelation. However, this does not apply to any random person claiming to prophethood rather more signs are also required, for example the previous sign mentioned of Surah Yunus. Some non Ahmadi Muslims have tried to claim that these refer to Muhammadsaw alone, but this is false. How can we use this as an argument for his truthfulness, if it is confined to himsaw? If this shows the truthfulness of the Holy Prophetsaw, it can also be used to judge another persons truthfulness. The claimant must seriously be claiming propheethood and would have to attribute the revelation to Allah and should announce the revelations to th world as well. His previous life should also be clear of any lie or dishonest act. This refers to when the person has claimed revelation from Allah, rather than when they first claimed prophethoood. Ahmadas received his first revelation in the late 1860s and passed away in 1908, showing that he was indeed a truthful prophet. Allah continued to reveal to him till his last breath, and continued to bless his progeny and his followers. Allah is with this community, as it is His Own community and is continuing to Bless this Jamaat.
Ahmadas states:
“O ye people, be certain that I am being helped by a Hand Which shall always support me. If your men and your women, your youth and your elders, your commoners and your elite, all join together to pray for my destruction, to the extent that through constant prostrations noses start to rot and hands become useless, even then Allah will not listen to your prayers and He will not stop until His will is accomplished. And even if not a single human being supports me, the angels of Allah will be with me(Ruhani Khazain Volume 17, Arbaeen page 400)
And:
“In this regard one of my friends, with the purest of intentions, presented the question that in the verse Lau taqauwwala ‘alaina only the Holy Prophetsawhas been addressed, and how can it be inferred therefrom that if another person forges a lie [against Allah] then he would also be destroyed? The answer I provided him is that this statement is presented asan argument; and among the many proofs of the truthfulness of prophethood, this is also a proof. As such, the statement of Allah is only proven true if a false claimant [to divine revelation] is destroyed, otherwise this statement cannot be an argument against those who disbelieve, nor can it be established as a proof before him. Rather, he can assert that the Holy Prophetsaw was not saved from destruction for 23 years because he was truthful. Instead, the reason is because forging a lie against God is not a sin for which He punishes anyone in this world. For if this was a sin and the Sunnah of Allah required that a false claimant be punished in this world, then there should have been examples of this, but you accept that there are no such examples. Quite the contrary, there are many examples where people forged lies against God for 23 years or even more, but they were not destroyed. Now tell us, what would be the response to such an allegation?”(Arbaeen IV, Ruhani Khazain Volume 17 page 434-435)
Heas also stated in his challenge:
” In Lahore, Hafiz Muhammad Yusuf Sahib, Dila‘dar of Canals, under the false doctrines of ignorant and misguided clerics, … has stated confidently that if anyone falsely claims to be a Prophet or a Messenger or a commissioned one by God, and thus seeks to mislead people, he can survive such imposture for twenty-three years and even more. What he means to say is that the survival of such an impostor for more than twenty-three years cannot be a proof of his truth. He also stated that he can cite the names of many people who made such false claims and continued to assert for more than twenty-three years that they were recipients of God’s word…. Through this announcement, I demand from Hafiz Muhammad Yusuf Sahib to cite such an instance as promised in his signed document. I know for certain that this principle, which is set out in the Holy Qur’an by God Himself, can never be contravened….
It is for this reason that I have made this public announcement together with an offer of five hundred rupees as an award for the citation of a single instance to the contrary, and I am prepared to deposit this amount in any government bank in advance. If Hafiz Muhammad Yusuf Sahib and those who think like him, whose names I have mentioned in this announcement, will cite an instance with adequate proof in accordance with the Holy Qur’an, in which a person who falsely claimed to be a Prophet or a Messenger or a commissioned one of God, continued to publish his alleged revelations for more than twenty-three years, I shall pay such a person the sum of five hundred rupees in cash. They will be at liberty to cite such an instance from anywhere in the world within a fortnight of the publication of this announcement.” (Arabain, No. III, Ruhani Khazain, Volume 17, Pages 387-402)
This belief of a one who claims he has received revelation, not being able to live for more than 23 years, is not only the belief of Ahmadi Muslims. Allama Sa’d’-ud-Din Taftazani wrote in Sharahul Aqaid:
” The Reason renders it impossible that these things should accumulate in any other than a Prophet, in a person about whom Allah the Exalted knows that he is fabricating a lie upon God and yet grant him a respite for 23 years.” (Sharah Ul Aqaid)
