Firstly, we can conclude that the penalty for a person is dead if he is an apostate. When a person claims to be a Muslim and then has the belief of another prophet after Prophet Muhammad (SAW), he becomes a murtad which makes the death penalty them. So now you have two options for Qadianis, either be a murtad and be dead or accept that you’re non-Muslim and enjoy minority rights. By accepting God they are better than atheists, yet the reason that Allah created this whole universe is to demonstrate His omnipotence by the finalization of Prophethood through Muhammad (SAWW) alone. They are now way better human beings. They defy the purpose of the creation of the universe.
In the 10 years of wars after Nadr, only 259 Sahaba (the companions of the prophet) had been martyred but only in Jang e Yamama, the battle against the false prophet, the liar Musailma, around 1400 sahaba alehesalam Ajmaeen got martyred. When scholars say that they’re to be given all the rights of minorities on the condition that they accept themselves to be minorities, they’re being generous in my opinion. This issue is no joke. Allah’s Apostle said,
The Hour will not be established till about thirty Dajjals (liars) appear, and each one of them will claim that he is Allah’s Apostle
This is what Prophet Muhammad (Peace be Upon him) said about the coming of false prophets. We can’t follow these false prophets or claim their followers one of us especially when prophet Muhammad told us not to! Well, Qadianis don’t accept Muhammad Pbuh as “Khatam Al Anbiya” according to what Prophet Muhammad (SAW) himself said: “la nabi ba’di”.
