Allah's Pardon

What’s the difference between Maghfirah (مغفرة ) and 'Afuw (عفو )?

Maghfriah: is for Allah to forgive you for the sin but the sin will still be registered on your book of deeds.
Maghfirah is Allah’s forgiveness for your sin but on the Judgment Day it will be written on your record, Allah will ask you about it but HE won’t punish you because of it

Afuw: is for Allah to forgive you for the sin and delete it from your book of deeds as if it did not happen.
Afuw is Allah’s pardon for your sin, it will be completely erased from your record and Allah won’t ask you about it on Judgement day

This is why our Prophet (salla Allahu alaihi wa sallam) said that, this is the best Duaa to make on Laylatul Qadr:

"Allahumma innaka 'afuwwun tuhibbul 'afwa fa'fu 'annee"
(Ahmad, Ibn Majah, and Tirmidhi)

O Allah, You are The One Who pardons greatly, and You love to pardon, so pardon me.)"

So make sure you read this dua all the time and as much as you can. Make it one of your daily athkaar.
