The phrases like purification and exit from darkness to light are applied instead of education in Quran. One of the following two verses refers to genetic education and the other to legislative education:
هُوَ الَّذِی یُصَلِّی عَلَیْکُمْ وَ مَلائِکَتُهُ لِیُخْرِجَکُمْ مِنَ الظُّلُماتِ اِلَى النُّورِ).
It is He who blesses you, and His angels, to bring you forth from the shadows into the light.(1)
We know that God's bless to His servants is his mercy and favors, and angels' bless seems to be the same mercy and blessings which are bestowed to the servants by angels, both having a genetic aspect and anyway their aim is leading from darkness of aberration towards the light of guidance.
هُوَ الَّذِی یُنَزِّلُ عَلى عَبْدِهِ آیات بَیِّنات لِیُخْرِجَکُمْ مِنَ الظُّلُماتِ اِلَى النُّورِ).
It is He who sends down upon His servant signs, clear signs, that He may bring you forth from the shadows into the light.(2)
In the above verse too, which refers to legislative education, leading from darkness to the light is considered as the purpose.
It is induced from this interpretation that a non-educated man resembles one being in absolute darkness. Such person possesses several potencies and talents but does not have any power for leading them, and orienting towards a goal. He can neither adopt a clear way, nor attain to the destination.
But when he is educated and trained, it is alike to going from darkness into the light. Light is the means of training and development and appearance of talents, and the means of leadership and orientation and targeting, and so all concepts and meanings of education are included in this interpretation.
