Then We sent after him Messengers to their people, and they came to them with Clear Explanation; but they were not believed in That which they had rejected before, thus We seal upon the hearts of aggressors.
All the 313 Messengers have been sent with Adhikr—the Clear Explanation and Truth—to warn mankind that there is no deity except Allah and to serve Him alone as told in verses 21: 24-25. It is told about hypocrites in verse 63: 3 that they believed and then they disbelieved; so, Lord has sealed upon their heart; thus, they don’t understand the aim of life. Only such transgressing people will hide Adhikr—the Food, Cloth and Sight of the human soul— from mankind as explained in verse 2: 99. The Hell will be filled with these aimless hypocrites and their heedless followers as explained in verses 7: 179. While the odd-believer who testifies Adhikr is trying to propagate It to entire worlds to benefit the 1000 communities of Lord’s creatures, the worst creatures—the hypocrites and Kuffar mentioned in verse 8: 22—try to extinguish the Light Adhikr. But Lord will fill His Light even though disbelievers hate It as explained in verses 9: 32-33. See the explanations 2: 6-7, 18; 6: 25-26 and 10: 33.
