Narrated by As-Sa’-ib bin Yazid
I was in the company of Talha bin ‘Ubaidullah, Sad, Al-Miqdad bin Al-Aswad and ‘Abdur Rahman bin ‘Auf (radiallaahu `anhum) and I heard none of them narrating anything from Allah’s Apostle (sallallaahu `alayhi wasallam) except Talha who was talking about the day (of the battle) of Uhud.
The sahaba were careful about quoting the Prophet (sallallaahu `alayhi wasallam) for fear of adding something to it or forgetting part of it. It was because of his words:
Sahaba would never even think of fabricating ahadith. This was just a precaution some of them took. There were others like Aisha, Abu Huraira, Ibn Abbas etc. who narrating many ahadith from the Prophet (sallallaahu `alayhi wasallam) in order to spread his teachings.
In this day and age, it’s easy to confirm the authenticity of a report that is attributed to the Prophet (sallallaahu `alayhi wasallam). It is our duty to make use of the available tools to confirm before broadcasting.
Read here the ruling on the one who tells lies against the Prophet (sallallaahu `alayhi wasallam).
