And if they don't respond to you, then you know that this is revealed with the Knowledge of Lord Allah and that there is no deity except Him; then would you become those who submit wholly to Lord?
It is told in verses 21:24-25 that all 313 Messengers were sent with Adhikr (the Truth and Proof) to inform the people that there is no deity except Lord Allah; so, you serve Him alone. Three-Time-Knowledge Adhikr is the Guidance, Mercy, and Herald for those who submit wholly to the Lord, as explained in verse 16:89. It is the Explanation from the Lord of the universe, as explained in verse 7:52. Since Adhikr is the Best Interpretation of the Lord’s Book, as told in verse 25:33, the Arabic Quran-reading Fujjar who hide and reject It will be dragged prone on their faces into Hell. They are in the worst place and are the most strayed, as told in verse 25:34. See explanation 2:136, 186; 3:19, and 4:82.
