quran:46:13 –

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

Assuredly those who say, ‘Our Lord is God’ and then remain upright, in ˹their adherence to˺ obedience, no fear will befall them, nor will they grieve.
القرآن:٤٦:١٣ –

إِنَّ الَّذِينَ قَالُوا رَبُّنَا اللَّهُ ثُمَّ اسْتَقَامُوا فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ  

{إن الذين قالوا ربنا الله ثم استقاموا} على الطاعة {فلا خوف عليهم ولا هم يحزنون}.
