Those are the ones who have lost their soul and strayed from what they have been forging.
The Arabic Quran-reading Fujjar are not considering the soul or the Hereafter. They are only giving preference to bodily and worldly life, as explained in verses 14:2-3. The hypocrites among the Mujirims, by converting Adhikr into disbelief, have made Hell (the house of worthless) Halal for their followers, as explained in verses 3:196-197. The believer shouldn’t obey these disbelievers in any case and shouldn’t choose them as patrons, as explained in verse 4:144. These soulless and worthless Fujjar will witness against their souls that indeed they were disbelievers at the time of their death, as noted in verse 7:37, and on the Day of Judgment, as noted in verse 6:130. See explanation 2:121; 6:94 and 7:53.
