There’s a beautiful du’a that Allah mentions near the end of Surah Baqarah:
وَا عْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا
Translation:So do ‘affuw on us. And forgive us. And have mercy on us. [Baqarah 2:286]
Allah mentions three things, in order:
‘Affuw ‘annaa: Affuw linguistically means to erase something; to obliterate something; to completely destroy something and leave no traces of it whatsoever. This du’a is saying: make affuw of our sins. Remove them completely.
Waghfirlanaa: Ghafira linguistically means toprotect–that’s why a helmet is called a mighfaar. Read up about Allah’s two names: Al-Ghafuwr and Al-Ghaffaar. Here, the du’a is saying: and if you do not ‘affuw our sins, forgive us, and protect us from the consequences of them.
