And surely We have brought for them a Book, We have explained It upon My Knowledge, a Guidance and a Mercy for the believing people.
Adhikr is the only Book sent from Lord to 313 Messengers to teach mankind that there is no deity except Lord and to serve Him alone as explained in verses 21: 24-25. Adhikr is the Three-Time-Knowledge of the Three-Time-Knower Lord which explains everything. It is codified through the Three-Time-Knower mentioned in verse 25: 59. It is also the Best Interpretation of the Lord’s Book. So whoever from the Arabic Quran reading Fujjar rejects It, they will be dragged prone on their faces into Hell, those are in the worst place and they are the most strayed as explained in verses 25: 33-34. The Fujjar will only accept the fact that not the Arabic Quran but Adhikr was the Lord's Book when they are being slain by the other people belonging to the Messenger's community after the second coming of Jesus as explained in verses 4: 91.
Only one in a thousand becomes a believer who utilizes Adhikr as the Guidance, Mercy, and Herald as explained in verse 16: 89. So whomever holdfasts the Safeguard Adhikr, he did holdfast the Safeguard Lord and is guided into the Straightpath. Verses 7: 203, 12: 11, and 16: 64 also end as Adhikr is a Guidance and Mercy for the believing people. See explanation 1: 7; 6: 134, 155-157; 16: 43 and 27: 77.
