(At-twur) 52 : 15
أَفَسِحْرٌ هَٰذَا أَمْ أَنْتُمْ لَا تُبْصِرُونَ
Is this a delusion, or can’t you see?
it is told in verses 102: 5-7 that those who do not utilize Adhikr-the Insight of soul and the Confirming Truth-will see the fire till they get confirmed. See explanation 32: 12; 38: 55-64; and 50: 22.
