How a Companion of the Prophet is Identified ?

How a Companion of the Prophet -sallAllaahu alayhi wa sallam-   is Identified
By Miseekah bint ‘Assim al-Quruti
Translated by Abbas Abu Yahya 

‘The Companions can be known in a number of different ways:

1- Sometimes the Companions can be known by being mentioned in the Noble Qur’aan, like the saying of Allaah Ta’ala:

<<as one of two, when they were in the cave>> [Tawbah: 40]

the meaning of that is as-Siddiq –Radi Allaahu anhu– [Abu Bakr].

This is why the scholars say: ‘Whoever rejects Abu Bakr’s companionship of the Prophet -sallAllaahu alayhi wa sallam- is a disbeliever.’

Likewise the mention of the companionship of Zayed bin Harithah –Radi Allaahu anhu–due to the saying of Allaah Ta’ala:

<<So when Zayd had no longer any need for her, We married her to you>> [Ahzab: 37]

2 – By Tawatir (Recurring narratives) like the companionship of Umar, Uthmaan, Ali, Hudayfah, Abu Huriarah, ‘Aeysha and others from the senior Companions –Radi Allaahu anhum ajmaeen.
