伊斯兰教法的律例（Ahkam shar'iah）分为：fard（必行）、haram（禁戒）、mandoob（推荐）、makruh（憎恶）和mubah（允许）。Hukm shar'i（教法判定）要么是命令去做某事，要么是命令不做某事。如果做某事的命令（amr）是确定的（jazim），则归类为fard或wajib。这两个术语是同义的。如果做某事的命令是不确定的，则归类为mandoob。如果不做某事的命令是确定的，则归类为haram或maHzur，二者同义；而如果不做某事的命令是不确定的（ghair jazim），则归类为makruh。 因此，对于fard/wajib，履行者受到赞扬，放弃者受到谴责。疏忽而未履行fard的人应当受到惩罚。实施haram的人受到谴责，远离它的人受到赞扬。实施haram的人应当受到惩罚。履行mandoob的人受到赞扬并获得回报，而放弃它的人不受谴责，即他因履行该行为而获得回报，因放弃它而不受惩罚。不做makruh行为的人受到赞扬并获得回报，即远离makruh是更可取的。Mubah是指daleel as-Sam'ai（经文证据）表明立法者的言语意味着在做某事与不做某事之间有选择余地。

The AHkam shar’aiah are divided into: the fard (compulsory), the haram (prohibited), the mandoob (recommended), the makruh (undesirable) and the Mubah (permissible). The Hukm shar’ai is either an order to perform an action or to abstain from performing an action. If the order (amr) to perform the action is decisive (jazim), then it is classified as fard or wajib. Both these terms are synonymous. If the amr to do an action is indecisive, it is classified as mandoob. If the order to abstain is decisive, it is classified as haram or maHzur which are synonymous, whereas if the order to abstain is indecisive (ghair jazim), it is classified as Makruh. Thus, with the fard/wajib, the performer is praised and the one who abstains from it is condemned. The person who neglects to perform the fard deserves to be punished. The person who performs the haram is condemned and the one who abstains from it is praised. The person who performs the haram deserves to be punished. The person who performs the mandoob is praised and rewarded and the one who abstains is not condemned i.e. he is rewarded for performing the action and not punished for abstaining from it. The person who does not perform the makruh action is praised and rewarded i.e. abstaining from the makruh is preferable. The mubah is which the daleel as-Sam'ai (textual evidence) shows that the speech of the Legislator implies the choice between performing an action or abstaining from it.
