"The knowledge of a believer"

'Abdu Allaah ben Al-Mu'taz said:

علم المنافق في قوله وعلم المؤمن في عمله

ENGLISH:

"The knowledge of a hypocrite is in his speech, while the knowledge of a believer is in his actions."

NEDERLANDS:

"De kennis van de huigelaar (munafiq) presenteert zich in zijn woorden (qawl), en de kennis van de gelovige (mu'min) presenteert zich in zijn daden (amal)".

["Iqtidaa-u al'ilmi al'amal", 38].
