I think tht hadiths is talking someone that leave islam not nation and tribesAl-Bukhaari (6922) narrated that Ibn ‘Abbaas said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever changes his religion, put him to death.”
Al-Bukhaari (6484) and Muslim (1676) narrated that ‘Abd-Allaah ibn Mas’ood said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “It is not permissible to shed the blood of a Muslim who bears witness that there is no god except Allaah and that I am the Messenger of Allaah, except in one of three cases: a soul for a soul (i.e., in the case of murder); a previously-married person who commits zina; and one who leaves his religion and separates from the main body of the Muslims.”
The ruling of apostates in our religion is death. They're asked to repent, but if they don't they get put to death.
Once they leave Islam, they're not part of the ummah, hence not part of the Islamic nation. Is that so hard to understand?
Second u need to post jain narrations proof
And second there no ummah there is no such 1 community ppl are different nation and tribes not same
