ربَّنَا اغْفِرْ لَنَا ذُنُوبَنَا وَإِسْرَافَنَا فِي أَمْرِنَا وَثَبِّتْ أَقْدَامَنَا وانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ
"Our Lord! Forgive us our sins and our transgressions, establish our feet firmly, and give us victory over the disbelieving folk."
rabbanagh-fir lanaa dhunoobanaa wa israafanaa fee amrinaa wa thabbit aqdaamanaa wan-ṣurnaa ‛alaal-qawmil-kaafireen
