Surah Al-Anfal (The Spoils of War), Verse 2

اِنَّمَا الْمُؤْمِنُوْنَ الَّذِیْنَ اِذَا ذُكِرَ اللّٰهُ وَجِلَتْ قُلُوْبُهُمْ وَاِذَا تُلِیَتْ عَلَیْهِمْ اٰیٰتُهٗ زَادَتْهُمْ اِیْمَانًا وَّعَلٰی رَبِّهِمْ یَتَوَكَّلُوْنَ ۟

Innamal mu'minoonal lazeena izaa zukiral laahu wajilat quloobuhum wa izaa tuliyat 'alaihim Aayaatuhoo zaadat hum eemaananw wa 'alaa Rabbihim yatawakkaloon

“For, Believers are those who, when Allah is mentioned, feel a tremor in their hearts, and when they hear His signs rehearsed, find their faith strengthened, and put (all) their trust in their Lord;”
