Qur'anic Dua - 07 (English)
رَبَّنَا إِنَّنَا آمَنَّا فَاغْفِرْ لَنَا ذُنُوبَنَا وَقِنَا عَذَابَ النَّارِ
"Our Lord, indeed we have believed, so forgive our sins and protect us from the punishment of the Fire,"
This dua is mentioned in Surah Aal Imran aayah No. 16.
Before this dua, it is mentioned in the Quran that the pious people and the ones with whom Allah is pleased, they pray in this way.
So, for seeking forgiveness of sins and getting salvation from the Hellfire, we should also keep reading this dua of the pious people.
