Sa’eed ibn Jubayr said:
Indeed [true] fear is to fear Allaah until your fear [of Him] lies between you and your sins; that [there] is what fear is.
And [true] remembrance is obedience to Allaah. So whoever is obedient to Allaah, then he has remembered Him, and whoever is not obedient to Him, then he is not one who remembers [Him] – even if he exerts himself in glorifying Allaah and reciting the Qur.aan.
