رَبَّنَا اغْفِرْ لَنَا ذُنُوبَنَا وَإِسْرَافَنَا فِي أَمْرِنَا وَثَبِّتْ أَقْدَامَنَا وَانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ
Rabbana-ghfir lana dhunubana wa israfana fi amrina wa thabbit aqdamana wansurna 'alal-qawmil-kafirin
“Our Lord, forgive us our sins and our excess in our affairs, make our feet firm, and grant us victory over the disbelieving people.”
