Surah Al Anfal: 2-4
The believers are only those who, when Allah is mentioned, feel a fear in their hearts and when His Verses are recited to them, they increase their Faith; and they put their trust in their Lord;
Who perform As-Salat and spend out of that We have provided for them.
It is they who are the believers in truth. For them are grades of dignity with their Lord, and Forgiveness and a generous provision.
