‘Abdullah b. Mas’ûd (Allaah be pleased with
him) said:
“The believer sees his sins as if he is
sitting at the foot of a mountain fearing that it might fall on him, while the
sinner (fâjir) sees his sins as a fly that lands on his nose, he just waves it
away.”
Al-Bukhârî,
Al-Sahîh, The Book of Supplications, Chapter on Tawbah.
Ibn
Hajr quotes in his commentary, Fath Al-Bârî:
Ibn
Abî Jumrah said,
“The reason for this [fear] is that the
heart of a believer is illuminated; so when he sees from himself something that
goes against what he illuminates his heart with, it is very distressing to him.
The wisdom behind giving the example of a mountain is that a person might find
some way to escape from other dangers, but if a mountain falls on a person he
does not survive. In short, the believer is dominated by fear (of Allaah) due to
the strength of îmân he has; he does not therefore feel falsely secure about
being punished because of his sins. This is the way of the Muslim: he always
fears and checks on himself, his good deeds are little to him and he fears even the small bad deeds
he has done.”
