Al-Fawzaan: Some brothers, may Allaah forgive them, develop a grudge against someone, or hatred towards a student of knowledge or a scholar, so they will ask you a question which you [accordingly] answer—an answer which they then go and apply to that person, they go and apply it to that person and that you meant him [when you answered], so they will say, ‘So and so [i.e., the scholar] said such and such about so and so!’

[But when you [i.e., the scholar] were answering that question] neither ‘so and so’ nor ‘so and so’ or ‘so and so’ [even] came to your mind, you only answered a question.

They apply it like that and say, ‘He meant so and so! He meant such and such a group!’ And they dub the sound and write books [based on that], saying that, ‘Such and such [a scholar] said this and that about so and so and answered the question about such and such.’

Their intention behind that is to cause trouble between people and sow dissent among the students of knowledge and cause enmity between them.

So we warn them and ask Allaah to grant you refuge from this trait … that you are not deceived or fooled by it!

Be on your utmost guard against it.
