I just wonder . People usually act upon knowledges he acquired. Human are aware about the good and evil but still the hearts are keen and lean towards wrongdoings. Human Hearts always in deviations.
Human internally complicated all full of ambiguity. There always disparity and unparallel between mind, hearts and its actions. God reminded that we must often pray to HIM on our HEARTS.
' O Lord Let not our hearts deviate from the truth after You have guided us. And grant us mercy from You. Truly You are the Bestower.' (Ali Imran :8)
