When reading the Qur’an, I think we do a great injustice to our understanding by viewing it with the lens of our preconceived ideas/notions. For example, kafaroo = rejectors, so this must be speaking of those people who are not Muslim. How can you be so sure that you don’t fit into it? Just because you were born into a ‘Muslim’ family does not make you a Muslim. Your actions decide that. And it’s not a label that you can carry. It’s a lifetime struggle to TRY and become a Muslim. How dare you call yourself a Muslim when your actions are different to what our Creator wants from us? Do you even know what He wants from us?
Forget all that you’ve been taught and read the Book with an open mind. And then judge yourself and other people according to the teachings of it.
