but, to deny being a Muslim is to become apostate.
to be apostate is to be punished by death
But then, why is Obama still living?
For the same reason that Huma Abedin was allowed by her family to marry a Jew.
You see, the whole thing is very flexible depending on your agenda and as long as such allowances support that agenda.
It’s not apostate for a Muslim to lie if the reason is to further Jihad. There are reports of Muslims seeking refugee status in Europe claiming to have converted to Christ so they won’t be denied refugee status.
Has Obama ever publicly denied that he is a Muslim?
Has he ever once in his life uttered the words “Jesus Christ is Lord”?
Not if such a Muslim considers himself on a "jihad" and in the course of the jihad, if even lying about being a Muslim is necessary to continue the "holy war", then they wouldn't be committing the sin of apostasy. I think the term is "Taqqia" or something like that. "Justified lies".
This isn't Christianity we're talking about here.
