Can those who had been dead (ignorant), to whom We gave life and a light with which they can walk among people, be compared to those in complete darkness (polytheism and hypocrisy) from which they can never come out? That is how the misdeeds of the disbelievers have been made appealing to them.
Meaning:-
ignorant: lacking knowledge or awareness in general; uneducated or unsophisticated. lack of knowledge, understanding, or information about something.
Polytheists: The worship of or belief in more than one god, belief in many gods
hypocrisy: pretending to be what you are not, or pretending to believe something that you do not.
