Tafsir of Al-Mu'minoon 23:8

Those who are faithfully true to their Amanat and to their covenants, When they are entrusted with something, they do not betray that trust, but they fulfill it, and when they make a promise or make a pledge, they are true to their word. This is not like the hypocrites about whom the Messenger of Allah said:

آية المنافق ثﻼث

إذا حدث كذب

وإذا وعد أخلف

وإذا اوتمن خان

The signs of the hypocrite are three: when he speaks he lies, when he makes a promise he breaks it, and when he is entrusted with something he betrays that trust

والذين هم على صلواتهم يحافظون
