Shaykhul-Islām Ibn Taymiyyah, may Allāh have mercy upon him, said:
“A person may know that the truth is with someone else but in spite of this, he obstinately rejects it due to his envy of that person or due to him seeking to make himself uppermost over him or due to personal desires. And those desires lead him to transgress against him and reject what he is saying by any means (necessary) while within his heart he knows that the truth is with him.”
