The true believers are those who?

The true believers are those who, when Allah's name is mentioned, their hearts quake, and when His verses are recited to them their faith grows, and who put their trust in their Lord;who establish Prayer and spend out of what We have provided them.Such people are indeed true believers. They have high ranks with their Lord, and forgiveness for their sins and an honorable sustenance.
[8:2-4]

إنما المؤمنون الذين إذا ذكر اللـه وجلت قلوبهم وإذا تليت عليهم آياته زادتهم إيمانا وعلى ربهم يتوكلون ﴿٢﴾ الذين يقيمون الصلاة ومما رزقناهم ينفقون ﴿٣﴾ أولئك هم المؤمنون حقا ۚ لهم درجات عند ربهم ومغفرة ورزق كريم ﴿٤﴾ سورة الأنفال
