(blessings and peace be upon him) as saying: '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
Sahih Muslim Hadith 79
