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)
Referring to those who show themselves as believers but in fact are not, the Glorified Allah commands; “There are some people who say: We believe in Allah and the last day. In fact they are not believers at all. They want to deceive Allah and those who believe. But in fact they deceive only themselves and they do not recognize (it).” (Al-Baqara/ The Cow 2/ 8-9)
In the 7th verse of Al-Baqara it is declared that as a result of the disbelievers’ determination in disregarding Allah, they had started not to notice the truth as a habit so that the eyes of the disbelievers have been veiled. The same veil closes the hypocrites’ (munafik) eyes, too. The Glorified Allah commands:
“Their case is similar to the case of one who kindled a light. When it (the light) illumined all around him, Allah took away the light from their eyes, and left them in darkness– they do not see.
They are deaf, dumb, and blind. They won’t return.” (Al-Baqara/The Cow 2/ 17-18)
The verse shows that at the beginning they wanted to be enlightened with the divine instructions. But, when the instructions bring out the truths they are discomforted, what makes them disregard them and turn to darkness. They make themselves deaf, dumb, and blind. They don’t want to hear, see or speak about the truths. And they won’t return.
