Narrated by Abu Huraira (Radiyallahu `anhu) that the Prophet (Sallallaahu `alayhi wa sallam) said,
“If any one of you says, ‘Ameen’ and the angels in the heavens say ‘Ameen’ and the former coincides with the latter, all his past sins will be forgiven.”

Abu Dharr and Muadh bin Jabal (Radiyallahu `anhuma) reported that the Prophet (Sallallaahu `alayhi wa sallam) said,
“Fear Allah wherever you are, do good deeds after doing bad ones, the former will wipe out the latter, and behave decently towards people”

Abu Hurairah (Radiyallaahu `anhu) reported, I heard the Messenger of Allah (Sallallaahu `alayhi wa sallam) saying,
“By Allah, I seek Allah’s forgiveness and repent to Him more than seventy times a day.”

Narrated Abu Huraira (Radiyallaahu `anhu), Allah’s Apostle (Sallallaahu `alayhi wa sallam) said,
“If Allah wants to do good to somebody, He afflicts him with trials.”
