Mukhtasar Bukhari

´Sayyiduna Hudhaifah (may Allah be pleased with him) says that` hypocrisy existed until the time of the Noble Prophet (peace and blessings of Allah be upon him) (because Allah would inform him that such and such a person is a hypocrite), but in this era, a person is either a believer or a disbeliever (because the state of the heart is known to Allah; now matters are based on what is apparent).
