As for those who have accepted God’s guidance, He strengthens them in guidance (through deeper knowledge and submission), and gives them piety and protection from sinning
While as for those who wish to walk in the Light, He shows them the way all along, and secures for them their journey through life. ('Huda' = Brightness, light, guidance, beacon, showing the way, lead the lost)
And as for those who receive (Allah’s) guidance, He increases the (light of) guidance, and places on them their (true) Faith and (pure) control (away from evil)
As for those who follow true guidance He leads them far ahead in their right ways (in the light of His guidance) and grants them piety and restraints from evil suited to their condition
But to those who attain the reality, He expands their ability to experience the reality and enables them to protect themselves (from behaviors that go against or impede the experience of the reality).
Al-muntakhab fi tafsir al-Qur'an al-Karim
But those whose minds' eyes have led them to the path of safety and righteousness, Allah has justified faith as a conviction operative on their character and will and imprinted their deeds with wisdom and piety
