Forgiveness (Istighfar)

those who remember God and implore forgiveness for their sins if they do something shameful or wrong themselves- who forgives sins but God?- and who never knowingly persist in doing wrong.

Yet anyone who does evil or wrongs his own soul and then asks God for forgiveness will find Him most forgiving and merciful.

Ask forgiveness from your Lord, and turn to Him in repentance: my Lord is merciful and most loving.’

I said, “Ask forgiveness of your Lord: He is ever forgiving.
