(Al-Kahf) 18 : 87
قَالَ أَمَّا مَنْ ظَلَمَ فَسَوْفَ نُعَذِّبُهُ ثُمَّ يُرَدُّ إِلَىٰ رَبِّهِ فَيُعَذِّبُهُ عَذَابًا نُكْرًا
He said: "As for who does unjust, we will punish him; then he will be returned to his Lord, and He will punish him with a nasty punishment”.
There is no compulsion in the True Way of Life since the Lord is Impartial. So the believer who testifies Adhikr will not be partial among mankind. As there is no group of believers anywhere in the world, the odd believer follows a lifestyle explained in verses 2: 62 and 7: 205-206. See explanation 4: 150-151 and 9: 67-68.
