Hypocrisy means showing outwardly something other than what he feels or believes in his heart. It is divided into hypocrisy in belief and hypocrisy in deed. As for hypocrisy in belief, it means that a person conceals disbelief whilst making an outward show of being a Muslim. This is the hypocrisy for which a person will abide forever in the lowest level of Hell, and he is not counted among those who affirm the oneness of Allah. As for hypocrisy in deed, such a person does affirm the oneness of Allah, and he will not abide forever in Hell. In this hadith, the Prophet (blessings and peace of Allah be upon him) discussed hypocrisy in deed, and described its distinguishing characteristics. He said that there are four characteristics, and whoever has them is a pure hypocrite, in the sense that he closely resembles the hypocrites because of these characteristics. Whoever has one or some of them is a hypocrite to some degree, until he gives up these characteristics. The first characteristic is that he is well known among the people to be treacherous. The second characteristic is that he is well known for lying when he speaks. The third characteristic is that if he makes a promise he breaks it and does not fulfil the promise that he made. The fourth characteristic is resorting to foul speech and irrational talk when arguing. What is meant by that is that he deliberately rejects the truth, to the extent that what is true becomes false for him, and what is false becomes true. What the hadith means is that these characteristics are the characteristics of hypocrisy, and the one who has them is like the hypocrites in this regard, and has the same attitude as they do, not that he is a hypocrite who pretends to be a Muslim whilst inwardly disbelieving. When he mentioned hypocrisy in this hadith, the Prophet (blessings and peace of Allah be upon him) was not referring to the hypocrisy for which a person will be in the lowest depth of hell, which is the worst type of disbelief. Rather he meant that these characteristics are akin to the concept of hypocrisy, because hypocrisy means displaying outwardly something other than what is in one’s heart. This concept is applicable in the case of lying, breaking promises and betraying trusts. What is meant by the words “he is a pure hypocrite” is pure in the sense of having these characteristics that are mentioned in the hadith only, not other characteristics..
