“Illah（علة）是促使立法的Baa'ith（动因、理由），而Sabab（سبب）则是提示该Hukm在现实中存在的标志。它（Sabab）与为处理现实而立法的Hukm并无直接关联。

The ‘Illah is the Baa’ith (reason, motive) for the legislation whilst the Sabab is that which notifies of the presence of the Hukm within the reality. It (the Sabab) is not related to the legislation of the Hukm in order to treat the reality.

Example:

安拉塔阿拉说：

Allah Ta’Aalaa said:

太阳的西斜是礼拜正午礼拜（Zhohr）的原因（Sabab），所谓“Dulook”（太阳西斜）是指太阳从天空的中央偏移，以此作为确定正午礼拜时间到来的标志。

The decline of the sun is the Sabab for the presence of the Zhohr prayer and the ‘Dulook’ of the sun is when it declines from the centre of the sky as a sign to identify the presence of Salaat uzh-Zhohr.

虽然"علّة"（伊莱）是立法某一判决的理由或动机，但它并不是该判决存在于现实中的"سبب"（起因）。例如，主麻拜（Salaat ul-Jumu'ah）存在的起因是太阳偏离天空中央；而在拜功时间进行贸易被禁止的"علّة"则是"الإلهاء"（分心）。

This is whilst the ‘Illah is the reason or motive for the legislation of the Hukm and it is not a Sabab (cause) for its existence (in the reality). For example, the Sabab for the existence of Salaat ul-Jumu’ah is the decline of the sun from the centre of the sky whilst ‘Al-Ilhaa’’ (distraction) is the ‘Illah for the prohibition of conducting trade at the time of the Salaah.

因此,“Sabab”(原因)促使了主麻礼拜的确立。至于“‘Illah”(效验因由),则促使了与该礼拜相关的“Hukm”(律例)的确立。

Consequently, the Sabab brought Jumu’ah prayer into being. As for the ‘Illah then it brought the Hukm that is related to the prayer into being.

在"As-Sabab"（原因）的定义中，有如下一条：

From amongst the definitions of ‘As-Sabab’ is the following:

它是这样一种事物：其存在必然导致（该律例）的存在，其不存在必然导致（该律例）的不存在。因此，如果日中（太阳偏离天顶）已经出现，那么律例就已成立（即产生了效力）；如果尚未出现，那么（该义务）

It is that which necessitates from its existence the existence (of the Hukm) and necessitates through its absence the absence (of the Hukm). Consequently, if the Zawaal (decline of the sun from the meridian) has taken place then the Hukm has taken place (i.e. come into being) and if it hasn’t occurred then the (obligation of the)

礼拜尚未举行。

Salaah has not occurred.
