'He who amongst you sees something abominable should modify it with the help of his hand;
and if he has not strength enough to do that, then he should do it with his tongue;
and if he has not strength enough to do even that, then he should (at least abhor it) from his heart; and that is the least of faith
The above quotation was said by Prophet Muhammad (peace be upon him) Sahih Muslim Hadith 79 Narrated by Abu Sa'id al-Khudri
