Question
I work in a printing house owned by a Christian, and I print books and notebooks for Christianity. Is my salary halal or haram? If it is permissible for me to work for a lower salary, should I leave it?
Answer
I say, and with God's help: Your reward is lawful; because what you are doing is permissible in itself, but it is preferable that you do not continue working with him to avoid disagreement if another opportunity arises for you. And God knows best.
