Allāh, the Most High, has stated:
قُلْ هَلْ يَسْتَوِي الَّذِينَ يَعْلَمُونَ وَالَّذِينَ لَا يَعْلَمُونَ ۗ إِنَّمَا يَتَذَكَّرُ أُولُو الْأَلْبَابِ ﴿٩﴾
“Say: ‘Are those who know equal to those who know not?’ It is only men of understanding who will take heed.”
Knowledge is the shield and protection from sin and transgression for the Muslim. When the Muslim knows the difference between the truth and misguidance he can then distinguish between the people of Paradise and the people of the hellfire.
