In any war of ideas, you must command the language to shape the ideological battle space. The left and political Islam are experts at using the right words to win.
There is a word we must start using – Kafir, do not use unbeliever or non-Muslim. I did a study of the use of the word “kafir” in the Koran and found that it is used in nearly 400 verses. In 345 verses kafir means unbeliever and in 39 verses it means “ungrateful”. Kafir is the word Allah uses to describe us.
How do we know it is the right word? Simple. Muslims do not want us to use it. Using Kafir is a game changer. And while you are at it, use Koran, not Qur’an.
