You [believers] are more fearful within their breasts than Allah. That is because they are a people who do not understand.
The Saheeh International Quran Translation
لَأَنتُمْ أَشَدُّ رَهْبَةً فِى صُدُورِهِم مِّنَ ٱللَّهِ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَYou [believers] are more fearful within their breasts than Allah. That is because they are a people who do not understand.
