رَّبَّنَا إِنَّنَا سَمِعْنَا مُنَادِيًا يُنَادِي لِلإِيمَانِ أَنْ آمِنُواْ بِرَبِّكُمْ فَآمَنَّا رَبَّنَا فَاغْفِرْ لَنَا ذُنُوبَنَا وَكَفِّرْ عَنَّا سَيِّئَاتِنَا وَتَوَفَّنَا مَعَ الأبْرَارِ
Translation 
"Our Lord, indeed we have heard a caller calling to faith, [saying], 'Believe in your Lord,' and we have believed. So forgive us our sins, Our Lord, and remove from us our misdeeds and and make us die the death of the righteous."
