“Allah will never give the kafirun a way over the Muminun.” Qur’an 4: 140
While this particular ayat has application regarding the judiciary (a non-Muslim is not allowed to render judgment against a Muslim) it has additional applications.
One of the ways Allah denies the unbeliever “a way” over the faithful regards secret-keeping. Perhaps one thing which is not fully understood is that proper vetting and rank accomplished by humans are not the primary criteria for being entrusted with a secret and keeping the same.
My vetting process and investigation into my character and background were still incomplete when I took the oath of office and put on my uniform. It was understood that should anything surface after the fact, my clearance could be revoked – hence my inability to serve in official capacity as a Naval officer.
Islam… is different.
