Al-Ahqaf 46:13

Inna allatheena qaloo rabbunaAllahu thumma istaqamoo fala khawfunAAalayhim wala hum yahzanoon

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.

Surely, those who say, “Our Lord is Allah” and then stay firm, they will have no fear, nor shall they grieve.
