Surah Al-Ahqaf, ayah 13

46:13

إِنَّ ٱلَّذِينَ قَالُواْ رَبُّنَا ٱللَّهُ ثُمَّ ٱسۡتَقَٰمُواْ فَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ ١٣

Innal-ladhīna qālū rabbunallāhu thummastaqāmū falā khawfun 'alayhim walā hum yahzanūn

Indeed, those who have said, "Our Lord is Allāh," and then remained on a right course - there will be no fear concerning them, nor will they grieve.
