And thus We have sent down to you the Book, and those to whom We gave the Book before believing with It, and among these people are there who believe with It, and none repudiates Our verses except the disbelievers.
The Arabic Quran reading Fujjar are falsely boasting before other people that they are in truth. But by hiding and rejecting Adhikr (Straightpath) they have become the true disbelievers as explained in verses 4: 150-151. They are not transforming their Jinn soulmate mentioned in verse 43: 36-39 into a believer and are not changing their ledger from Sijjeen of Hell (83: 7) into Illiyeen of Paradise (83: 18) with Adhikr. They are denoted as the worst creatures as explained in verses 8: 22 and 55. They are denoted as filthy, and Adhikr will increase them nothing except filth over filth as explained in verses 9: 28, 95, and 125. See explanation 7: 50-51.
