On the Day We will call forth every people with their Leader; then whoever is given his Recorded Book in his right hand, those will read their records, and they will not be dealt with unjust even that much of a speck.
Adhikr is the Leader mentioned in this verse as well as in 11: 17; 36: 12 and 46: 12. But the believer will only testify the 40 names of Adhikr. Every man is fastened with a Recording Book around his neck which omits nothing without recording. On the Day of Judgment, it will be produced to him as an Illuminating Spread Open Book and it will be said to him: “You read your Book, Today, you are enough for Reckoning yourself” as explained in verses 17: 13-15. The believer who testifies Adhikr will only receive the Recorded Book in his right hand.
The Arabic Quran reading Fujjar have made their food ‘rejecting Adhikr’ as told in verse 56: 82. The hypocrites among the Fujjar will enter Hell without Trial whereas their blind followers Kuffar will enter Hell after Trial. On receiving the Recorded Book in the left hand, the Kuffar will wail as told in verse 18: 49. Inmates of Hell will blame, curse, and argue against each other as explained in verses 2: 165-167. See explanation 9: 5, 28; 15: 45-48 and 17: 60.
