Al-Mu'minun 23:109

إِنَّهُۥ كَانَ فَرِيقٌ مِّنْ عِبَادِى يَقُولُونَ رَبَّنَآ ءَامَنَّا فَٱغْفِرْ لَنَا وَٱرْحَمْنَا وَأَنتَ خَيْرُ ٱلرَّٰحِمِينَ

Innahu kāna farīqun min ʿibādī yaqūlūna rabbanā āmannā fa-igh'fir lanā wa-ir'ḥamnā wa-anta khayru l-rāḥimīna

Indeed, there was a party of My servants who said, 'Our Lord, we have believed, so forgive us and have mercy upon us, and You are the best of the merciful.'
