رَبَّنَا اغْفِرْ لَنَا وَلِإِخْوَانِنَا الَّذِينَ سَبَقُونَا بِالْإِيمَانِ وَلَا تَجْعَلْ فِي قُلُوبِنَا غِلًّا لِّلَّذِينَ آمَنُوا

Transliteration

Rabbanagh-fir lanaa wa li-ikhwaaninallazeena sabaqoonaa bil-eemaani wa laa taj'al fee quloobinaa ghillal-lillazeena aamanoo.

Meaning

Our Lord, forgive us and our brothers who preceded us in faith and put not in our hearts [any] resentment toward those who have believed. Our Lord, indeed You are Kind and Merciful.
