Ibn Mas’ood (ra) narrated:
“Indeed, the believer sees his sins as if he was standing
at the foot of a mountain fearing that it will fall upon him
and the sinner sees his sins like a fly which passes by his nose
so he tries to remove it by waving
his hand around.”
[Sahih al-Bukhari (6308) and Sahih Muslim (2744)]

Wait, out of curiosity, did Ibn Mas’ud say this this or is he the narrator before the Prophet, upon him blessings and peace?
As salaamu alaykum,
Jazakallah khair, I believe he is the narrator.
