Bismillaah:

Abu Umaamah رضي الله عنه said:

The Messenger of Allaah صلي الله عليه وسلم said:

The companion (i.e. Angel) on the left lifts his pen for six hours for the Muslim slave that errs or sins. If the slave is remorseful and asks Allaah’s forgiveness, the Angel does not record it. And if the slave does not ask Allaah for forgiveness, the Angel records it as one (sin).”
