Those are the true disbelievers and We have kept prepared heinous punishment for the disbelievers.
The Lord’s Book is revealed to form the true belief about the Creator Lord Allah, His Book, His Messengers, Satan, Angels, Day of Judgment, etc. Today Adhikr containing all the 312 previous Books and their upright explanations is codified through the Three-Time-Knower mentioned in verse 25: 59. It explains everything as told in verse 16: 89. Those who are hiding even the forty names of Adhikr such as Dhikra, Dhikree, Safeguard, Guidance, and Insight are the human devil hypocrites. And their followers who are rejecting It are the Fajir disbelievers. Both the hypocrites and their blind followers are called the Arabic Quran reading Fujjar. The so-called leaders among the Fujjar are denoted as hypocrites and their blind followers are denoted as disbelievers in the same verse such as in 4: 140; 33: 1, and 48. In verses such as 33: 73; 48: 6, and 98: 6, the followers of hypocrites are mentioned as Mushriks. In verses 9: 67-68, 73, and 66: 9 the followers are mentioned as Kuffar. In verses 2: 39; 5: 10, 86; 57: 10, and 64: 10 the followers are mentioned as rejecters. In verses 33: 60; 22: 53, and 74: 31 the followers are mentioned as those who are having a disease in their hearts. If the term ‘Fujjar’ is mentioned alone as in verses 82: 14 and 83: 7, it covers both the hypocrites and their blind followers. And if the term ‘Kuffar’ is mentioned alone as in verses 9: 123; 48: 29, and 83: 36, hypocrites and their blind followers are included in it.
The only Party of Lord from Adam to the Last Day is the party of believers in any era as told in verse 58: 22. The different groups of Fujjar who are reading these verses but are not following It are belonging to Satan’s party as told in verse 58: 19. They are the Fujjar who have made their food 'rejecting Adhikr' as explained in verse 7: 26.
In short, the disbelievers mentioned in 520 verses, the wrongdoers mentioned in 220 verses, Mujirims mentioned in 52 verses, hypocrites mentioned in 24 verses, transgressors mentioned in 38 verses, Mushriks mentioned in 55 verses are the Fujjar who have not become believers with Adhikr after receiving It. So, any Fujjar who didn’t testify Adhikr which is the Best Interpretation of the Book in his fourth phase will witness against his soul that indeed, he was a disbeliever at the time of his death vide verse 7: 37 and on the Day of Judgment vide verse 6: 130. The Fujjar will be dragged prone on their face into Hell, such are in the worst place and they are the most strayed as told in verses 25: 33-34. Lord has denoted the Fujjar as the worst creatures who don't utilize their intelligence to hear and talk about Adhikr as told in verse 8: 22.
Verse 4: 151 is the only verse saying: "Those are the true disbelievers. And verses 8: 4 and 8: 74 are the only verses that say: "Those are the true believers". Only the believer who transforms his Jinn soulmate into a believer with Adhikr can die by submitting wholly to Lord as explained in verse 8: 48. See explanation 1: 7; 2: 166-167, and 8: 55.
