Al-Anfal 8:2

إِنَّمَا ٱلۡمُؤۡمِنُونَ ٱلَّذِينَ إِذَا ذُكِرَ ٱللَّهُ وَجِلَتۡ قُلُوبُهُمۡ وَإِذَا تُلِيَتۡ عَلَيۡهِمۡ ءَايَٰتُهُۥ زَادَتۡهُمۡ إِيمَٰنٗا وَعَلَىٰ رَبِّهِمۡ يَتَوَكَّلُونَ 2

The believers are only those who, when Allah is mentioned, their hearts become fearful, and when His verses are recited to them, it increases them in faith; and upon their Lord they rely
