Our Position on Books That Speak About the Companions

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is our position, Honorable Shaykh, regarding books that speak about some of the Companions, disparaging and cursing them, and perhaps even belittling them, as in the book by Sayyid Qutb?

Answer:
In any case, if some of these books were written out of ignorance and by imitating others, then the author has erred and gone astray without a doubt. However, we do not declare him a disbeliever because he is ignorant and imitates others. But if he believes this, if he believes what he said, then he is a disbeliever.
As for if he said this out of ignorance and imitation, and if the truth were made clear to him, he would return, then it is said that he has gone astray and erred in this matter. It is upon us to respond to those who speak about the Companions. It is upon us to respond and clarify his error, so that others are not deceived by him, especially if he has a status and is described as a caller to Islam. Some people may be deceived by him, so it is necessary to respond to him and clarify his error. Yes.
