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 the ones who establish prayer and from what we have provided them they spend.
إنما المؤمنون الذين إذا ذكر الله وجلت قلوبهم وإذا تليت عليهم آياته زادتهم إيمانا وعلى ربهم يتوكلون الذين يقيمون الصلاة ومما رزقناهم ينفقون
