Is it permissible to take knowledge from one who says that Shaykh Muhammad ibn 'Abd al-Wahhab did not engage in da'wah, but rather others did?

Question:
Some people say that Shaykh Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him) did not do anything of da'wah, but rather others did it. What is the ruling on this statement? And is its author someone from whom it is considered permissible to take knowledge?

Answer:
This denies clear matters in which there is no doubt, so he is of no account. He is either mentally deficient, having no intellect, denying the established principles, or he is an enemy who denies out of envy and misguiding people. What the Shaykh did is clear, there is no doubt in it, and its effects remain, praise be to Allah. Yes, so do not pay attention to this fool who says this statement. He is either ignorant, and it is not permissible to take knowledge from him, or he is misguided, and it is not permissible to take knowledge from the people of misguidance. Yes.
