رَبَّنَا وَاجْعَلْنَا مُسْلِمَيْنِ لَكَ وَمِنْ ذُرِّيَّتِنَٓا اُمَّةً مُسْلِمَةً لَكَۖ وَاَرِنَا مَنَاسِكَنَا وَتُبْ عَلَيْنَاۚ اِنَّكَ اَنْتَ التَّوَّابُ الرَّحٖيمُ
Meaning
Our Lord, and make us Muslims [in submission] to You and from our descendants a Muslim nation [in submission] to You. And show us our rites and accept our repentance. Indeed, You are the Accepting of repentance, the Merciful.
