they only are the believers whose hearts feel fear when allah is mentioned and when his revelations are recited unto them they increase their faith and who trust in their lord who establish worship and spend of that we have bestowed on them.
إنما المؤمنون الذين إذا ذكر الله وجلت قلوبهم وإذا تليت عليهم آياته زادتهم إيمانا وعلى ربهم يتوكلون الذين يقيمون الصلاة ومما رزقناهم ينفقون
