Dua For Inner Peace

The best dua is the one which is made from the core of your heart. Dua doesn’t necessarily need to be in Arabic as Allah understands all languages.
Below is a special dua from Quran that you can also make relating to your needs.

رَبَّنَا لَا تُؤَاخِذْنَآ إِن نَّسِينَآ أَوْ أَخْطَأْنَا ۚ رَبَّنَا وَلَا تَحْمِلْ عَلَيْنَآ إِصْرًۭا كَمَا حَمَلْتَهُۥ عَلَى ٱلَّذِينَ مِن قَبْلِنَا ۚ رَبَّنَا وَلَا تُحَمِّلْنَا مَا لَا طَاقَةَ لَنَا بِهِۦ ۖ وَٱعْفُ عَنَّا وَٱغْفِرْ لَنَا وَٱرْحَمْنَآ ۚ أَنتَ مَوْلَىٰنَا فَٱنصُرْنَا عَلَى ٱلْقَوْمِ ٱلْكَـٰفِرِينَ

Transliteration :

Laa yukalliful-laahu nafsan illaa wus’ahaa; lahaa maa kasabat wa ‘alaihaa maktasabat; Rabbanaa laa tu’aakhiznaaa in naseenaaa aw akhtaanaa; Rabbanaa wa laa tahmil-‘alainaaa isran kamaa hamaltahoo ‘alal-lazeena min qablinaa; Rabbanaa wa laa tuhammilnaa maa laa taaqata lanaa bih; wa’fu ‘annaa waghfir lanaa warhamnaa; Anta mawlaanaa fansurnaa ‘alal qawmil kaafireen

Translation :

“Our Lord! Punish us not if we forget or fall into error, our Lord! Lay not on us a burden like that which You did lay on those before us; our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us Forgiveness. Have mercy on us. You are our Maula (Patron, Supporter and Protector, etc.) and give us victory over the disbelieving people.”
