Among all the different disciplines discussed here, the way the jurists use the word Sunnah is closest to its lexical definition. This usage, meaning "a praiseworthy way of action," has actually turned out to be a source of confusion concerning the status and importance of the sunnah.  Jurists, for the most part, are concerned with the rulings of particular actions. In general, an act may be classified into one of five categories: obligatory, recommended, permissible, reprehensible or forbidden. In addition, an act may be sound and valid or it may be void and non-effective. The scholars use a myriad of terms to describe the category of recommended acts. These terms included mandoob مندوب, mustahabb مستحبّ, and so on. In some cases, each term has a slightly different connotation.  However, without a doubt, one of the most common terms used for that category is the word "sunnah." Therefore, for example, the jurists will say that the two rak'atayn before the the obligatory Fajr (Dawn) prayer are "sunnah." This means that they are not obligatory. Yet they carry a certain status or reward for them such that they are definitely more than merely permissible.
