(Al-Qalam) 68 : 33
كَذَٰلِكَ الْعَذَابُ ۖ وَلَعَذَابُ الْآخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا يَعْلَمُونَ
Just like that the punishment, while the punishment of the Hereafter is the greatest, if they were having the Knowledge.
The Fujjar who are hiding Allah in His Book by hiding and rejecting Adhikr, and who are following the footsteps of Satan, are promised with disgrace in this world and severe punishment in the Hereafter through the verses 2: 85; and 5: 33. See explanation 10: 124-127; 34: 19-20; and 39: 25-26.
