To have read a lot about your faith and still not practice what you believe are the correct teachings out of sheer laziness or feeling its too much trouble to do/implement
OR
To be ignorant about your faith and never read about its teachings, but claim to be an adherent to it due to whatever limited knowledge you have been taught about your faith, which you hold dear.
Which is worse, if any? Thanks in advance for your reply.
Learn to love yourself, then learn to love one-another
First one is hypocrit and second one is ignorant. Both are undesirable, because the most important thing --- "amal or practice" is missing in both cases.
One should atleast have a clear intention, Allah's help will be there for you.
And you could say laziness is an excuse for both, i.e. lazy to act upon what you know, and in the second instance, lazy to seek knowledge as we are commanded to do.
