有两种关于“圣门弟子”（Sahabi）的定义：

There are two definitions of a Sahabi:

1. 一位见过先知（saw）的穆斯林。

1. A Muslim who saw the Prophet (saw).

2. 与先知（ﷺ）共同生活一两年，或参加过一两次先知（ﷺ）亲自率领的伽宰瓦特（军事远征）的穆斯林。

2. A Muslim who lived with the Prophet (saw) for one or two years or participated in one or two Ghazwaat (military expeditions led by the Prophet [saw]).

后一种定义由著名的再传弟子赛义德·本·穆塞布所传述，且更为可靠。据传他曾说：“一个人必须与先知ﷺ相伴一年或两年，或者曾随他参加过一两次战役，才能被称为圣门弟子。”舒尔巴转述穆萨·本·西比拉尼的话（舒尔巴对此人颇为推崇）说：他曾对阿nas·本·马立克（愿真主喜悦他）说：“除了您之外，真主的使者ﷺ还有其他同伴在世吗？”他回答说：“还有许多见过他的阿拉伯人在世。至于他的同伴，已经没有了！”伊玛目马兹尼在其著作《证据注解》中说：“我们所说的圣门弟子，并不是指与他见过一两天面的人，也不是指因某事来到他身边然后离去的人，而是指那些追随他、帮助他、并由真主（至高无上）启示给他ﷺ的光明所引导的人，这些人才能获得福祉。”

The latter definition was reported by the famous scholar of the Tabi‟een, Said bin al-Musayeb and is stronger. It has been narrated he said, “It is essential that someone has companionship with the Prophet (saw) for one or two years, or has gone out with him on one or two battles.” Shu'ba reported from Musa al-Sibillani - whom he spoke appreciatively about - that he said: “I said to Anas bin Malik (ra). Are there any companions of the Messenger of Allah (saw) left other than you? He said: There are still many Arabs who saw him. As for his companions, no!” Imam al-Mazini said in his book Sharh ul-Burhan, “We do not mean by Sahabah those who met him for a day or two, or those who attended him for some business and then left, we mean those who followed him, helped him and were guided by the light that Allah (swt) revealed to him (saaw), those are the ones to attain felicity.”
