"Ijma‟"（伊吉玛）是阿拉伯语动词 Ajmaa 的动名词，该动词有两个含义：1）决定；2）就某事达成一致。

Ijma‟ is the verbal noun of the Arabic word Ajmaa, which has two meanings: 1) to determine, 2) to agree upon something.

在伊斯兰教法根源学（Usul al-Fiqh）的著作中，讨论了许多种类的伊jma'（公议）。其中包括：伊jma'al-Ummah（整个乌玛的公议）、伊jma'al-Mujtahideen（穆哲台希德的公议）、伊jma'Ahl al-Bayt（先知家族的公议）、伊jma'al-Madinah（麦地那人的公议）以及伊jma'as-Sahabah（圣门弟子的公议）。其中，只有伊jma'as-Sahabah是确定无疑且为各方所一致认可的。

There are many types of Ijma‟ discussed in the books of Usul al-Fiqh. Some of these are; Ijma‟ al Ummah, Ijma‟ al Mujtahideen, Ijma‟ ahlel Bayt, Ijma al Madinah and Ijma‟ as-Sahabah. Ijma‟ as-Sahabah is the only one that is definitive and agreed upon.

如果圣门弟子(愿真主喜悦他们)在先知(愿真主赐福他并使他平安)去世后,对某个问题在《古兰经》和《逊奈》中没有明文裁定的情况下,一致同意某种解决办法,彼此之间没有任何异议,那么这种一致意见被视为一项证据(Daleel)。这一致意见必定基于先知穆罕默德ﷺ的某项教导,而这项教导是他们所有人都知道的,但并未以圣训的形式直接传到我们这里。因此,圣门弟子的公议(Ijma‟ as-Sahabah)是逊奈本身的一种迹象。

If the Sahabah (ra) after the death of the Prophet (saw) were to agree unanimously upon a solution to a problem without any dissent amongst each other, in the absence of a ruling from the Qur‟an and Sunnah, then this agreement is considered to be a Daleel. This agreement must have been based upon some teaching of Mohammed (saw) of which they all knew, but which did not reach us directly in the form of Hadith. Therefore, Ijma‟ as-Sahabah is an indication of Sunnah itself.
