إِنَّمَا المُؤمِنونَ الَّذينَ إِذا ذُكِرَ اللَّهُ وَجِلَت قُلوبُهُم وَإِذا تُلِيَت عَلَيهِم آياتُهُ زادَتهُم إيمانًا وَعَلىٰ رَبِّهِم يَتَوَكَّلونَ

The believers are those whose hearts tremble when God is mentioned, whose faith is strengthened when His verses are recited to them, and who trust their Lord.
