The ‘munafik’ is the name given to a person who first believes, later begins to disregard Allah, but still thinks or shows himself as a believer. The Glorified Allah commands: “When the hypocrites come to you, they say: We bear witness that you are most surely Allah’s Messenger. Allah knows that you are most surely His Own Messenger. Allah bears witness that those hypocrites are surely lying.
They make their oaths a shelter and thus turn away from Allah’s path. How evil is that they do.
That is, because they first believed, later disbelieved, then their hearts were altered. So, they do not understand.” (Al-Munafiqoon/The Hypocrites 63/1-3)
They are deaf, dumb, and blind. They won’t return.” (Al-Baqara/The Cow 2/ 17-18)
