Apostate prophet seeks counterexamples; the fate of false prophets in history?

In answer to the video "Who (Really) Wrote The Quran?"

For example Musaylima emerged shortly after the Prophet's death and was killed under the orders of Abu Bakr. Before him and contemporaneous to the prophet was Saf Ibn Sayyad. He would eventually be completely discredited and in fact convert to Islam.

Another one was Bahaullah - though later his followers branched off into the Bahai faith which is based on the nice concept of unity of religions- he died a prisoner of the Ottoman Empire. There is also Mirza Ghulam Ahmad from Qadian, Punjab - his death is widely cited to be from either one of these diseases - cholera, diarrhoea, plague, or dysentery. Besides numerous prophecies regarding the timing and manner of his death were left unfulfilled - though Ahmadis now intrepret those in a metaphorical manner- but the manner of death is hardly inspiring for one claiming to be a Prophet.

There is then Rashad Khalifa who was a modern claimant based on his theory of the number 19's pattern in the Quran. Well, besides being accused of paedophilia, he was assassinated and his theories entirely discredited.

But above all, their theories did not prevail and either remained confined to a small number of followers or were simply lost and forgotten shortly after their death.

Another modern claimant was Joseph Smith in the US who started the Latter Day Saints movement and is the founder of Mormonism. He too was unfortunately assassinated. As a side note even the Mormon story has more grounds to stand on from the point of view of authenticity, than the NT story, in that there are actually known then-living individuals who executed an affidavit saying that they had, themselves, seen something of the Mormon story whereas the NT is written by anonymous people with no first hand information decades after the alleged, unsubstantiated life of the NT Jesus.

Of all the new religions that have sprung up after Islam, one may perhaps say Sikhism is also there. But Guru Nanak, the founder of the Sikh faith, never claimed for himself Prophethood. Also, Sikhism emerged as a reform movement intertwined between Hinduism and Islam. The holy book Guru Granth contains quotes from Sufi saints as well.

One may also mention the case of Paul of Tarsus.

On the face of it, finality of Prophethood seems to be a tenuous claim. After all, potentially anyone can stand up and say that he is a Prophet of God - but so far all the instances in which this has happened has failed to even come close to the scale and scope of the Prophet Muhammad's mission.

Also, if we examine the entire career of these claimants - they have singularly and absolutely failed to match the life-chart of Prophet Muhammad and moreover their death poses even more questions than their life. What is even more interesting that none of them claimed to be the final Prophet, much less Jesus who predicted the coming of a powerful figure after him, the Paraclete, that shall bring justice to the world.
