Knowledge is not to be taken from four types of people: a foolish person who openly acts foolish, even if he reports the most narrations; an adherent of bid'ah who calls to his desires; a person who lies, even if I don't accuse him of lying in hadith; and a righteous pious worshiper who does not accurately retain what he narrates.
