Allah is the first teacher and the absolute guide of humanity
“And Allâh has brought you out from the wombs of your mothers while you know nothing. And He gave you hearing, sight, and hearts that you might give thanks (to Allâh)" [Surah an-Nahl 16: Verse 78]
True knowledge is knowledge that brings us closer to Allah (swt)
Then we understand the purpose of our existence
Surah Adh Dhariyat 51: Verse 56 وَمَا خَلَقْتُ الْجِنَّ وَالْإِنسَ إِلَّا لِيَعْبُدُونِ And I (Allah) created not the Jinn and The Mankind except that they should worship Me (Alone).
Those who have knowledge are aware of this truth & act accordingly, thereby having a beneficial impact on those around them Those who are ignorant fumble through the world, vainly attempting to satisfy their desires, following Shaytan, & ultimately failing to understand their purpose & duty in this life.
"Say: 'Are those who know equal to those who know not?' It is only men of understanding who will remember (that is get a lesson from Allah's signs)." [Az-Zumar, 39:9]
