2:17 “Their likeness is as the likeness of one who kindled a fire; then, when it illuminated all around him, Allah removed their light and left them in darkness. they could not see”.
Allah likened the hypocrites when they bought deviation with guidance, to the example of a person who started a fire. When the fire was lit, illuminated the area & the person felt safe, it was suddenly extinguished and total darkness covered him. The person thus became unable to see anything or find his way out of this darkness.
Further, this person could not hear or speak and became so blind that even if there were light, he would not be able to see. This is why he cannot even return to the state that he was in before this happened to him. Such is the case with the hypocrites who preferred misguidance over guidance, deviation over righteousness.
“Allah removed their light” Allah removed what benefits them, the light, & left them with what harms them, the darkness and smoke.
“And left them in darkness”, that is their doubts, disbelief and hypocrisy.
“they could not see” meaning, they are unable to find the correct path or find its direction.
2:18 “They are deaf, dumb, and blind, so they return not (to the right path)”.
In addition, they are, “deaf” and thus cannot hear the guidance, “dumb” and cannot utter the words that might benefit them, “and blind” in total darkness and deviation. So they cannot get back to the state of guidance since they sold it for misguidance.
