الْخَشْيَةِ وَالتُّقَى
Reverent fear of Allah and piety.
مُخَالَفَةِ الْهَوَى
Resisting the desires of the self.
When desire urges a person toward disobedience, restraint and obedience express piety. Mulazamat al-awla adds steady commitment to the better course of action.
These qualities explain differences in the spiritual excellence and conduct of believers.
