Quran 3:193 from Surah Aal-i-Imraan on Divine Marvels.
رَّبَّنَآ إِنَّنَا سَمِعۡنَا مُنَادِيٗا يُنَادِي لِلۡإِيمَٰنِ أَنۡ ءَامِنُواْ بِرَبِّكُمۡ فَـَٔامَنَّاۚ رَبَّنَا فَٱغۡفِرۡ لَنَا ذُنُوبَنَا وَكَفِّرۡ عَنَّا سَيِّـَٔاتِنَا وَتَوَفَّنَا مَعَ ٱلۡأَبۡرَارِ
English translation: Our Lord indeed we [we] heard a caller calling to the faith that Believe in your Lord so we have believed Our Lord so forgive for us our sins and remove from us our evil deeds and cause us to die with the righteous
