Explaining the Denial of Evil with the Heart

Question:
He says: Your Eminence the Shaykh, it is well known that the lowest level of denying evil is with the heart. We ask for a definition of denial with the heart and how it is done, because many of us, including myself, are ignorant of this. May Allah protect you?

Answer:
First, one denies with his hand, then with his tongue, then with his heart. The Prophet (peace and blessings be upon him) said: If he is able, such as a ruler, such as a committee, such as a man with his family, he changes it with his hand with his children. If he is not able, he denies with his tongue: “This is not permissible,” “This is obligatory,” “This is not permissible.” He teaches him that this is an evil. He denies with his tongue. If he is unable, he denies with his heart; he does not attend the evil, because if he attends it and remains silent, that is proof that he permits this thing. So if he is not able to deny the evil, he leaves the gathering, by the saying of Allah the Exalted: “Do not say to this…” He denies the denial. If he is unable, he says: If he cannot, or if they did not hear him deny and did not respond, he says.
