For the Sufis, the “hypocrite” (munafiq) is not only the one who gives himself airs of piety in order to impress people, but in a general way, one who is profane, who does not draw all the consequences that are implied in the Dogma and the Law, hence the man who is not sincere, since he is neither consequential nor whole; now Sufism (tasawwuf) is nothing other than sincerity (sidq) and the “sincere” (siddiqun) are none other than the Sufis.
