Questions on the Explanation of the Book of Nullifiers of Islam

Question:
What is the difference between psychological aversion to something and religious aversion?

Answer:
Psychological aversion is what a person dislikes in his soul, even if he dislikes it religiously, but he dislikes it psychologically because it is heavy for him, it is difficult for him. Jihad is difficult for him, spending in the cause of Allah is difficult for him. How many people are free from this? This is not considered apostasy, because he did not dislike what Allah revealed; he only disliked doing the act, he only disliked doing the act, because of its heaviness on his soul.
