Al-Maani'（المانع）在语言上的含义：指阻止他物并对其构成阻碍的事物。

Al-Maani’ linguistically: It is what prevents and is obstructive to other than it.

根据术语的含义(术语定义):

The meaning in accordance to the Istilaah (Terminological definition):

这是伊斯兰教立法者（Shaari'）所规定的：某一哈昆（Hukm，法律裁定）的缺失，取决于某一条件的存在；或者，哈昆之因（Sabab，原因）的缺失，取决于它的存在。也就是说，若该因存在，则该哈昆不存在；或者说，该哈昆之因不存在。

It is what the Shaari’ has made the absence of the Hukm resultant from its presence or the absence of the Sabab (cause) of the Hukm resultant from its existence (i.e. if it exists the Hukm does not exist or the Sabab for the Hukm does not exist).

Example:

Example:

经期（الحيض）是妇女礼拜的障碍（مانع）。

Al-Haid (menstruation) is a Maani’ (preventer) for the woman’s Salaah.

债务构成天课应纳Nisaab（起征点）的阻碍（Maani'），若债务使所持财产的数额低于Nisaab，则债务即构成这一阻碍。

The debt represents a Maani’ (preventer) for the attainment of the Nisaab of the Zakaah if the debt reduces the amount under the Nisaab.
