That is because indeed when you were called to Allah (the Single) you disbelieved, and while to associate others with His dominion, you believed, then the right for Judgement is to Allah, the Highest, the Greatest.
The Fujjar are reading verses 16: 43-44; 21: 24 and 41: 43, which say that Adhikr—the Truth and Proof—is the only Book revealed to all 313 Messengers. But they have divided themselves into many organizations and groups and are included in Satan’s party, as mentioned in verse 58: 19. The verses they saw, read, and heard will argue and witness against them and will push them into Hell. By rejecting the Three-Time Knowledge, Adhikr, these Mujirims serve Satan and follow his footsteps, as explained in verses 2: 168-169 and 36: 59-62. See explanation 2: 113; 9: 67-68; 17: 45-46.
