Allah swt says “Their likeness is that of one who kindled a fire, and then when it had lit up all around them, Allah removed their light and left them in darkness, unable to see” (2:17)
“Ponder carefully His saying, "Allah removed their light, how He did not say, "Allah removed their fire”, such that the wording would conform to that found at the beginning of this verse. Why is this? Fire has both the property to give light and the property to burn, so its property of light was removed leaving only the property to burn and harm.”

The sahabi that knew the names of the munafiqun was Hudhayfah (RA), Muhammad ﷺ had disclosed this information only to him.
“Hudhayfah once heard a person saying, O Allah, destroy the hypocrites!' He said, Son of my brother, were He to destroy the hypocrites you would find yourself walking down roads alone, because hardly anybody would be left!'”
"Umar bin al-Khattab said to Hudhayfah, i ask you by Allah, did the Messenger of Allah count me as one of them? He replied, No, and I will not answer this question for any other after you”
Umar (ra) was able to find out indirectly who the hypocrites were. If anyone among the Muslims died, Umar would ask: "Has Hudhayfah attended his funeral prayer?" If the reply was 'yes', he would perform the prayer. If the reply was 'no', he became doubtful about the person and refrained from performing the funeral prayer for him.
