When the words are in a third language it can’t be akin to something in your own language like “I accept Jesus as my”. Being akin would be if those words were in Latin.

Again in the other video you linked to commentators say that he pronouces shahadat slightly different from how Turks generally say that. Therefore they don’t believe he’s even Turkish or his real name is Ergun Caner.
That’s how their technique goes. That technique is balloney.

Anyhow good for you having learned your Muslim prayers down pat and making them as easy as breathing. Congratulations.
