Al-Ahqaf 13

إِنَّ ٱلَّذِينَ قَالُوا۟ رَبُّنَا ٱللَّهُ ثُمَّ ٱسْتَقَـٰمُوا۟ فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

inna alladhīna qālū rabbunā l-lahu thumma is'taqāmū falā khawfun ʿalayhim walā hum yaḥzanūna

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.
